    The instability in protoplanetary disks due to gas-dust friction and self-gravity of gas and dust is investigated using linear analysis. In the case where the dust-to-gas ratio is enhanced and turbulence is weak, the instability grows, even in gravitationally stable disks, on a timescale of order 104-5 yr at a radius of order 100 AU. If we ignore the dynamical feedback from dust grains in the gas equation of motion, the instability reduces to the so-called "secular gravitational instability," which was investigated previously to be an instability of dust in a fixed background gas flow. In this work, we solve the equations of motion for both gas and dust consistently and find that long-wavelength perturbations are stable, in contrast to the secular gravitational instability in the simplified treatment. This may indicate that we should not neglect small terms in the equation of motion if the growth rate is small. The instability is expected to form ring structures in protoplanetary disks. The width of the ring formed at a radius of 100 AU is a few tens of AU. Therefore, the instability is a candidate for the formation mechanism of observed ring-like structures in disks. Another aspect of the instability is the accumulation of dust grains, and hence the instability may play an important role in the formation of planetesimals, rocky protoplanets, and cores of gas giants located at radii ~100 AU. If these objects survive the dispersal of the gaseous component of the disk, they may be the origin of debris disks.

    In this article, we present a state-of-the-art algorithm for solving the relativistic viscous hydrodynamics equation with the QCD equation of state. The numerical method is based on the second-order Godunov method and has less numerical dissipation, which is crucial in describing of quark-gluon plasma in high-energy heavy-ion collisions. We apply the algorithm to several numerical test problems such as sound wave propagation, shock tube and blast wave problems. In sound wave propagation, the intrinsic numerical viscosity is measured and its explicit expression is shown, which is the second-order of spatial resolution both in the presence and absence of physical viscosity. The expression of the numerical viscosity can be used to determine the maximum cell size in order to accurately measure the effect of physical viscosity in the numerical simulation.

    We investigate the formation of close-in terrestrial planets from planetary embryos under the influence of a hot Jupiter (HJ) using gravitational N-body simulations that include gravitational interactions between the gas disk and the terrestrial planet (e.g., type I migration). Our simulations show that several terrestrial planets efficiently form outside the orbit of the HJ, making a chain of planets, and all of them gravitationally interact directly or indirectly with the HJ through resonance, which leads to inward migration of the HJ. We call this mechanism of induced migration of the HJ "crowding-out." The HJ is eventually lost through collision with the central star, and only several terrestrial planets remain. We also find that the efficiency of the crowding-out effect depends on the model parameters; for example, the heavier the disk is, the more efficient the crowding-out is. When planet formation occurs in a massive disk, the HJ can be lost to the central star and is never observed. On the other hand, for a less massive disk, the HJ and terrestrial planets can coexist; however, the companion planets may be below the detection limit of current observations. In both cases, systems with a HJ and terrestrial planets have little chance of detection. Therefore, our model naturally explains the lack of companion planets in HJ systems regardless of the disk mass. In effect, our model provides a theoretical prediction for future observations; additional planets can be discovered just outside the HJ, and their masses should generally be small.

    We perform a linear perturbation analysis of expanding shells driven by expansions of H II regions. The ambient gas is assumed to be uniform. As an unperturbed state, we develop a semi-analytic method for deriving the time evolution of the density profile across the thickness. It is found that the time evolution of the density profile can be divided into three evolutionary phases: deceleration-dominated, intermediate, and self-gravity-dominated phases. The density peak moves relatively from the shock front to the contact discontinuity as the shell expands. We perform a linear analysis taking into account the asymmetric density profile obtained by the semi-analytic method, and imposing the boundary conditions for the shock front and the contact discontinuity while the evolutionary effect of the shell is neglected. It is found that the growth rate is enhanced compared with previous studies based on the thin-shell approximation. This is due to the boundary effect of the contact discontinuity and asymmetric density profile that were not taken into account in previous works.

    We investigate the gravitational fragmentation of expanding shells driven by H II regions using the three-dimensional Lagrangian simulation codes based on the Riemann solver, called Godunov smoothed particle hydrodynamics. The ambient gas is assumed to be uniform. In order to attain high resolution to resolve the geometrically thin dense shell, we calculate not the whole but a part of the shell. We find that perturbations begin to grow earlier than predicted by linear analysis under the thin-shell approximation. The wavenumber of the most unstable mode is larger than that in the thin-shell linear analysis. The development of the gravitational instability is accompanied by the significant deformation of the contact discontinuity. These results are consistent with a linear analysis presented by Iwasaki et al. that have taken into account the density profile across the thickness and approximate shock and contact discontinuity boundary conditions. We derive useful analytic formulae for the fragment scale and the epoch when the gravitational instability begins to grow.

    The formation and evolution of the circumstellar disk in unmagnetized molecular clouds is investigated using three-dimensional hydrodynamic simulations from the prestellar core until the end of the main accretion phase. In collapsing cloud cores, the first (adiabatic) core with a size of gsim3 AU forms prior to the formation of the protostar. At its formation, the first core has a thick disk-like structure and is mainly supported by the thermal pressure. After the protostar formation, it decreases the thickness gradually and becomes supported by the centrifugal force. We found that the first core is a precursor of the circumstellar disk with a size of >3 AU. This means that unmagnetized protoplanetary disk smaller than <3 AU does not exist. Reflecting the thermodynamics of the collapsing gas, at the protostar formation epoch, the first core (or the circumstellar disk) has a mass of ~0.005-0.1 M sun, while the protostar has a mass of ~10-3 M sun. Thus, just after the protostar formation, the circumstellar disk is about 10-100 times more massive than the protostar. In the main accretion phase that lasts for ~105 yr, the circumstellar disk mass initially tends to dominate the protostellar mass. Such a massive disk is unstable to gravitational instability and tends to show fragmentation. Our calculations indicate that the low-mass companions may form in the circumstellar disk in the main accretion phase. In addition, the mass accretion rate onto the protostar shows a strong time variability that is caused by the torque from the low-mass companions and/or the spiral arms in the circumstellar disk. Such variability provides an important signature for detecting the substellar mass companion in the circumstellar disk around very young protostars.

    In this paper, we study the Cauchy problem of the linearized kinetic equations for the models of Marle and Anderson-Witting, and compare these dispersion relations with the 14-moment theory. First, we propose a modification of the Marle model to improve the resultant transport coefficients in accordance with those obtained by the full Boltzmann equation. Using the modified Marle model and Anderson-Witting model, we calculate dispersion relations that are kinetically correct within the validity of the BGK approximation. The 14-moment theory that includes the time derivative of dissipation currents has a causal structure, in contrast to the acausal first-order Chapman-Enskog approximation. However, the dispersion relation of the 14-moment theory does not accurately describe the result of the kinetic equation. Thus, our calculation indicates that keeping these second-order terms does not simply correspond to improving the physical description of the relativistic hydrodynamics.

    Recent gamma-ray observations of middle-aged supernova remnants revealed a mysterious broken power-law spectrum. Using three-dimensional magnetohydrodynamic simulations, we show that the interaction between a supernova blast wave and interstellar clouds formed by thermal instability generates multiple reflected shocks. The typical Mach numbers of the reflected shocks are shown to be Msime 2 depending on the density contrast between the diffuse intercloud gas and clouds. These secondary shocks can further energize cosmic-ray particles originally accelerated at the blast-wave shock. This "two-step" acceleration scenario reproduces the observed gamma-ray spectrum and predicts the high-energy spectral index ranging approximately from 3 to 4.

    We analyze the physical processes of gap formation in an inviscid protoplanetary disk with an embedded protoplanet using a two-dimensional local shearing-sheet model. The spiral density wave launched by the planet shocks and the angular momentum carried by the wave is transferred to the background flow. The exchange of the angular momentum can affect the mass flux in the vicinity of the planet to form an underdense region, or gap, around the planetary orbit. We first perform weakly nonlinear analyses to show that the specific vorticity formed by shock dissipation of the density wave can be a source of mass flux in the vicinity of the planet and that the gap can be opened even for low-mass planets unless the migration of the planet is substantial. We then perform high-resolution numerical simulations to check analytic consideration. By comparing the gap-opening timescale and type I migration timescale, we propose a criterion for the formation of underdense region around the planetary orbit that is qualitatively different from previous studies. The minimum mass required for the planet to form a dip is twice as small as previous studies if we incorporate the standard values of type I migration timescale, but it can be much smaller if there is a location in the disk where type I migration is halted.

    By constructing a global model based on three-dimensional local magnetohydrodynamical simulations, we show that the disk wind driven by magnetorotational instability (MRI) plays a significant role in the dispersal of the gas component of protoplanetary disks. Because the mass loss timescale of the MRI-driven disk winds is proportional to the local Keplerian rotation period, a gas disk dynamically evaporates from the inner region, possibly creating a gradually expanding inner hole, while a sizable amount of the gas remains in the outer region. The disk wind is highly time dependent with a quasi-periodicity of several times the Keplerian rotation period at each radius, which will be observed as the time variability of protostar-protoplanetary disk systems. These features persistently hold even if a dead zone exists because the disk winds are driven from the surface regions where ionizing cosmic rays and high energy photons can penetrate. Moreover, the predicted inside-out clearing significantly suppresses the infall of boulders to a central star and the type I migration of proto-planets, which are favorable for the formation and survival of planets.

    We investigate the formation process of planetesimals from the dust layer by the gravitational instability in the gas disk using local N-body simulations. The gas is modeled as a background laminar flow. We study the formation process of planetesimals and its dependence on the strength of the gas drag. Our simulation results show that the formation process is divided into three stages qualitatively: the formation of wake-like density structures, the creation of planetesimal seeds, and their collisional growth. The linear analysis of the dissipative gravitational instability shows that the dust layer is secularly unstable although Toomre's Q value is larger than unity. However, in the initial stage, the growth time of the gravitational instability is longer than that of the dust sedimentation and the decrease in the velocity dispersion. Thus, the velocity dispersion decreases and the disk shrinks vertically. As the velocity dispersion becomes sufficiently small, the gravitational instability finally becomes dominant. Then wake-like density structures are formed by the gravitational instability. These structures fragment into planetesimal seeds. The seeds grow rapidly owing to mutual collisions.

    We use resistive magnetohydrodynamical (MHD) simulations with the nested grid technique to study the formation of protoplanetary disks around protostars from molecular cloud cores that provide the realistic environments for planet formation. We find that gaseous planetary-mass objects are formed in the early evolutionary phase by gravitational instability in regions that are decoupled from the magnetic field and surrounded by the injection points of the MHD outflows during the formation phase of protoplanetary disks. Magnetic decoupling enables massive disks to form and these are subject to gravitational instability, even at ~10 AU. The frequent formation of planetary-mass objects in the disk suggests the possibility of constructing a hybrid planet formation scenario, where the rocky planets form later under the influence of the giant planets in the protoplanetary disk.

    We investigate gas accretion on to a protoplanet, by considering the thermal effect of gas in three-dimensional hydrodynamical simulations, in which the wide region from a protoplanetary gas disc to a Jovian radius planet is resolved using the nested grid method. We estimate the mass accretion rate and growth time-scale of gas giant planets. The mass accretion rate increases with protoplanet mass for Mp < Mcri, while it becomes saturated or decreases for Mp > Mcri, where Mcri ≡ 0.036MJup(ap/1 au)0.75, and MJup and ap are the Jovian mass and the orbital radius, respectively. This accretion rate is typically two orders of magnitude smaller than that in two-dimensional simulations. The growth time-scale of a gas giant planet or the time-scale of the gas accretion on to the protoplanet is about 105 yr, that is two orders of magnitude shorter than the growth time-scale of the solid core. The thermal effects barely affect the mass accretion rate because the gravitational energy dominates the thermal energy around the protoplanet. The mass accretion rate obtained in our local simulations agrees quantitatively well with those obtained in global simulations with coarser spatial resolution. The mass accretion rate is mainly determined by the protoplanet mass and the property of the protoplanetary disc. We find that the mass accretion rate is correctly calculated when the Hill or Bondi radius is sufficiently resolved. Using the oligarchic growth of protoplanets, we discuss the formation time-scale of gas giant planets.

    We study the linearized kinetic equation of relaxation model proposed by Bhatnagar, Gross and Krook [P. L. Bhatnagar, E. P. Gross and M. Krook, Phys. Rev. 94 (1954), 511] (also called BGK model) and solve the dispersion relation. Using the solution of the dispersion relation, we analyze the relaxation of the macroscopic mode and kinetic mode. Since the BGK model is not based on the expansion in the mean free path in contrast to the Chapman-Enskog expansion, the solution can describe the accurate relaxation of initial disturbance with any wavelength. This nonrelativistic analysis gives suggestions for our next work on the relativistic analysis of relaxation.

    Numerical simulations for the non-linear development of Kelvin-Helmholtz instability in two different density layers have been performed with the particle-based method (Godunov SPH) developed by Inutsuka. The Godunov SPH can describe the Kelvin-Helmholtz instability even with a high-density contrast, while the standard SPH shows the absence of the instability across a density gradient. The interaction of a dense blob with a hot ambient medium has been performed also. The Godunov SPH describes the formation and evolution of the fingers due to the combinations of Rayleigh-Taylor, Richtmyer-Meshkov and Kelvin-Helmholtz instabilities. The blob test result coincides well with the results of the grid-based codes.
    An inaccurate handling of a density gradient in the standard SPH has been pointed out as the direct reason of the absence of the instabilities. An unphysical force happens at the density gradient even in a pressure equilibrium, and repulses particles from the initial density discontinuity. Therefore, the initial perturbation damps, and a gap form at the discontinuity. The unphysical force has been studied in terms of the consistency of a numerical scheme. Contrary to the standard SPH, the momentum equation of the Godunov SPH does not use the particle approximation, and has been derived from the kernel convolution or a new Lagrangian function. The new Lagrangian function used in the Godunov SPH is more analogous to the real Lagrangian function for continuum. The momentum equation of the Godunov SPH has much better linear consistency, so the unphysical force is greatly reduced compared to the standard SPH in a high density contrast.

    The fragmentation process in collapsing clouds with various metallicities is studied using three-dimensional nested-grid hydrodynamics. Initial clouds are specified by three parameters: cloud metallicity, initial rotation energy and initial cloud shape. For different combinations of these parameters, we calculate 480 models in total and study cloud evolution, fragmentation conditions, orbital separation and binary frequency. For the cloud to fragment during collapse, the initial angular momentum must be higher than a threshold value, which decreases with decreasing metallicity. Although the exact fragmentation conditions depend also on the initial cloud shape, this dependence is only modest. Our results indicate a higher binary frequency in lower metallicity gas. In particular, with the same median rotation parameter as in the solar neighbourhood, a majority of stars are born as members of binary/multiple systems for <10-4Zsolar. With initial mass <0.1Msolar, if fragments are ejected in embryo from the host clouds by multibody interaction, they evolve to substellar-mass objects. This provides a formation channel for low-mass stars in zero- or low-metallicity environments.

    The gravitational instability of a dust layer is one of the scenarios for planetesimal formation. If the density of a dust layer becomes sufficiently high as a result of the sedimentation of dust grains toward the midplane of a protoplanetary disk, the layer becomes gravitationally unstable and spontaneously fragments into planetesimals. Using a shearing box method, we performed local N-body simulations of gravitational instability of a dust layer and subsequent coagulation without gas and investigated the basic formation process of planetesimals. In this paper, we adopted the accretion model as a collision model. A gravitationally bound pair of particles is replaced by a single particle with the total mass of the pair. This accretion model enables us to perform long-term and large-scale calculations. We confirmed that the formation process of planetesimals is the same as that in the previous paper with the rubble pile models. The formation process is divided into three stages: the formation of nonaxisymmetric structures; the creation of planetesimal seeds; and their collisional growth. We investigated the dependence of the planetesimal mass on the simulation domain size. We found that the mean mass of planetesimals formed in simulations is proportional to L 3/2 y , where Ly is the size of the computational domain in the direction of rotation. However, the mean mass of planetesimals is independent of Lx , where Lx is the size of the computational domain in the radial direction if Lx is sufficiently large. We presented the estimation formula of the planetesimal mass taking into account the simulation domain size.

    Formation of interstellar clouds as a consequence of thermal instability is studied using two-dimensional two-fluid magnetohydrodynamic simulations. We consider the situation of converging, supersonic flows of warm neutral medium in the interstellar medium that generate a shocked slab of thermally unstable gas in which clouds form. We find, as speculated in Paper I, that in the shocked slab magnetic pressure dominates thermal pressure and the thermal instability grows in the isochorically cooling, thermally unstable slab that leads to the formation of H I clouds whose number density is typically n lsim 100 cm-3, even if the angle between magnetic field and converging flows is small. We also find that even if there is a large dispersion of magnetic field, evolution of the shocked slab is essentially determined by the angle between the mean magnetic field and converging flows. Thus, the direct formation of molecular clouds by piling up warm neutral medium does not seem to be a typical molecular cloud formation process, unless the direction of supersonic converging flows is biased to the orientation of mean magnetic field by some mechanism. However, when the angle is small, the H I shell generated as a result of converging flows is massive and possibly evolves into molecular clouds, provided gas in the massive H I shell is piled up again along the magnetic field line. We expect that another subsequent shock wave can again pile up the gas of the massive shell and produce a larger cloud. We thus emphasize the importance of multiple episodes of converging flows, as a typical formation process of molecular clouds.

    Protostellar outflow is a star's first cry at the moment of birth. The outflows have an indispensable role in the formation of single stars because they carry off the excess angular momentum from the center of the shrinking gas cloud, and permit further collapse to form a star. On the other hand, a significant fraction of stars is supposedly born as binaries with circumbinary disks that are frequently observed. Here, we investigate the evolution of a magnetized rotating cloud using a three-dimensional resistive MHD nested-grid code, and show that the outflow is driven by the circumbinary disk and has an important role even in the binary formation. After the adiabatic core formation in the collapsing cloud core, the magnetic flux is significantly removed from the center of the cloud by the Ohmic dissipation. Since this removal makes the magnetic braking ineffective, the adiabatic core continuously acquires the angular momentum to induce fragmentation and subsequent binary formation. The magnetic field accumulates in the circumbinary disk where the removal and accretion of magnetic field are balanced, and finally drives the circumbinary outflow. This result explains the spectacular morphology of some specific young stellar objects such as L1551 IRS5. We can infer that most of the bipolar molecular outflows observed by low density tracers (i.e., CO) would correspond to circumbinary or circum-multiple outflows found in this Letter, since most of the young stellar objects are supposed to be binaries or multiples.

    We examine emission from a young protostellar object (YPO) with three-dimensional ideal magnetohydrodynamic (MHD) simulations and three-dimensional non-local thermodynamic equilibrium line transfer calculations, and show the first results. To calculate the emission field, we employed a snapshot result of an MHD simulation having young bipolar outflows and a dense protostellar disk (a young circumstellar disk) embedded in an infalling envelope. Synthesized line emission of two molecular species (CO and SiO) shows that subthermally excited SiO lines as a high-density tracer can provide a better probe of the complex velocity field of a YPO, compared to fully thermalized CO lines. In a YPO at the earliest stage when the outflows are still embedded in the collapsing envelope, infall, rotation, and outflow motions have similar speeds. We find that the combined velocity field of these components introduces a great complexity in the line emissions through varying optical thickness and emissivity, such as asymmetric double-horn profiles. We show that the rotation of the outflows, one of the features that characterizes an outflow driven by magneto-centrifugal forces, appears clearly in velocity channel maps and intensity-weighted mean velocity (first moment of velocity) maps. The somewhat irregular morphology of the line emission at this youngest stage is dissimilar to a more evolved object such as young Class 0. High angular resolution observation by, e.g., the Atacama Large Millimeter/submillimeter Array telescope can reveal these features. Our results demonstrate a powerful potential of the synthesized emission of the three-dimensional line transfer to probe the velocity field embedded in the envelope, and further analysis will be able to determine the precise velocity field to assess the dynamics in the YPO to gain a better understanding of star formation.

    We investigate the effects of viscosity on disk-planet interaction and discuss how type I migration of planets is modified. We have performed a linear calculation using shearing-sheet approximation and obtained the detailed, high-resolution density structure around the planet embedded in a viscous disk with a wide range of viscous coefficients. We use a time-dependent formalism that is useful in investigating the effects of various physical processes on disk-planet interaction. We find that the density structure in the vicinity of the planet is modified and the main contribution to the torque comes from this region, in contrast to the inviscid case. Although it is not possible to derive total torque acting on the planet within the shearing-sheet approximation, the one-sided torque can be very different from the inviscid case, depending on the Reynolds number. This effect has been neglected so far but our results indicate that the interaction between a viscous disk and a planet can be qualitatively different from an inviscid case and the details of the density structure in the vicinity of the planet are critically important.

    The standard scenario for the formation of planets has two critical problems: (1) Turbulence in the disk stirs up dust particles and prevents the dust sedimentation onto the disk mid-plane that is required for the fragmentation of the dusty layer prior to planetesimal formation. (2) The gravitational interaction of (proto)planets and the disk tends to result in their migration onto the central star within a short timescale. These problems have stimulated extensive theoretical work but still remain to be solved. In contrast, the recent increase of our understanding of the star formation process enables us to depict the long-term evolution of protoplanetary disks: the resultant gravitational fragmentation and the formation of gaseous planetary-mass objects in the disks. We critically review recent progress in our understanding of these processes and propose a possible hybrid scenario for the formation of planetary-mass objects in variety.

    Brown dwarf formation and star formation efficiency are studied using a nested grid simulation that covers 5 orders of magnitude in spatial scale (104-0.1 AU). Starting with a rotating magnetized compact cloud with a mass of 0.22 M sun(225 M Jup), we follow the cloud evolution until the end of the main accretion phase. An outflow of ~5 km s-1 emerges ~100 yr before the protostar formation and does not disappear until the end of the calculation. The mass accretion rate declines from ~10-6 M sun yr-1 to ~10-8-10-12 M sun yr-1 in a short time (~104 yr) after the protostar formation. This is because (1) a large fraction of mass is ejected from the host cloud by the protostellar outflow and (2) the gas escapes from the host cloud by the thermal pressure. At the end of the calculation, 74% (167 M Jup) of the total mass (225 M Jup) is outflowing from the protostar, in which 34% (77 M Jup) of the total mass is ejected by the protostellar outflow with supersonic velocity and 40% (90 M Jup) escapes with subsonic velocity. On the other hand, 20% (45 M Jup) is converted into the protostar and 6% (13 M Jup) remains as the circumstellar disk. Thus, the star formation efficiency is epsilon = 0.2. The resultant protostellar mass is in the mass range of brown dwarfs. Our results indicate that brown dwarfs can be formed in compact cores in the same manner as hydrogen-burning stars, and the magnetic field and protostellar outflow are essential in determining the star formation efficiency and stellar mass.

    We examine magnetohydrodynamic simulations of the propagation of a strong shock wave through the interstellar two-phase medium composed of small-scale cloudlets and diffuse warm neutral medium in two-dimensional geometry. The preshock two-phase medium is provided as a natural consequence of the thermal instability that is expected to be ubiquitous in the interstellar medium. We show that the shock-compressed shell becomes turbulent owing to the preshock density inhomogeneity, and magnetic field amplification takes place in the shell. The maximum field strength is determined by the condition that plasma β ~ 1, which gives the field strength on the order of 1 mG in the case of shock velocity ~103 km s-1. The strongly magnetized region shows filamentary and knotlike structures in two-dimensional simulations. The spatial scale of the regions with a magnetic field of ~1 mG in our simulation is roughly 0.05 pc, which is comparable to the spatial scale of the X-ray hot spots recently discovered in supernova remnants where the magnetic field strength is indicated to be amplified up to the order of 1 mG. This result may also suggest that the turbulent region with a locally strong magnetic field is expected to be spread out in the region with frequent supernova explosions, such as in the Galactic center and starburst galaxies.

    We investigate the motion of a particle around a low-mass planet embedded in a nonturbulent gaseous disk. We take into account the effect of the gas structure that is modified by the gravitational interaction between the planets. We derive an analytic formula that describes the change of the semimajor axis of the particle due to the encounter with the planet using local approximation in a distant encounter regime. Our final formula includes the effects of steady, axisymmetric radial gas flow, the global gas pressure gradient in the disk, planet gravity, and the structure of the gas flow modified by the planet's gravity. We compare the analytic results with numerical calculations and indicate that our formula well describes the secular evolution of the dust particles' semimajor axes well, especially for small particles with large drag coefficients. We discuss the conditions for dust gap opening around a low-mass planet and radial distribution of dust particles. Our formula may provide a useful tool for calculating radial distribution of particles in a disk around the planet.

    The radioactive isotope 60Fe (T 1/2 = 1.5 Myr) was present in the early solar system. It is unlikely that it was injected directly into the nascent solar system by a single, nearby supernova (SN). It is proposed instead that it was inherited during the molecular cloud (MC) stage from several SNe belonging to previous episodes of star formation. The expected abundance of 60Fe in star-forming regions is estimated taking into account the stochasticity of the star-forming process, and it is showed that many MCs are expected to contain 60Fe (and possibly 26Al [T 1/2 = 0.74 Myr]) at a level compatible with that of the nascent solar system. Therefore, no special explanation is needed to account for our solar system's formation.

    配分額:290670円 ( 直接経費:290670円 )

    3次元の磁気流体力学シミュレーションの手法で現実的な星間媒質における超新星残骸の形成および進化に対する研究を行う。これまでの研究の多くは爆発によって生成した衝撃波が密度が一様に分布した非現実的な星間空間を伝播してく状況を考えるか、現実的な密度非一様性を含んではいても局所的な計算に留まっていた。本研究では現実的でかつ大域的なシミュレーションを行うことによって、観測と直接比較することが可能な超新星残骸のシミュレーションデータを取得し、実験や観測事実の理解の深化を目指す。
    超新星残骸は宇宙線の加速現場であると考えられており、また星間空間へのエネルギー放出としても主要な成分となっており、それがどのように進化するのかは宇宙物理学にとって極めて重要な問題になっている。歴史的には超新星残骸の進化理論は一様な星間媒質に超新星爆発の噴出物が広がるモデルをベースとして発展してきた。しかしながら、実際の星間媒質は一般に非常に非一様であり、非一様なガス中を衝撃波が広がると衝撃波下流で乱流が発生し、その乱流を起源として粒子加速に必要な磁場増幅が発生したり、衝撃波下流のダイナミクスが変更を受けたりする。本研究では非一様な星間媒質を初期条件として超新星残骸がどのように進化するのかを、時間依存する計算格子を取り入れて分解能を落とさないように工夫した3次元の流体力学シミュレーションを行うことによって研究した。計算コードはFLASHと呼ばれる公開コードをベースに計算格子の空間サイズがが時間と共に大きくなるように基礎方程式に変更を加えるモジュールを独自開発して加えた。シミュレーションは成功し、星間媒質が一様な場合と非一様な場合の両方について計算機上に年齢が500年の超新星残骸を再現することに成功した。データを解析し、超新星残骸の主にX線による観測結果を比較した結果、衝撃波と接触不連続面の間の平均距離や、逆行衝撃波と順行衝撃波の間の膨張速度プロファイルなどの観測量は非一様な星間媒質を考えないと説明できないことが明らかとなった。
    3次元の大極的な超新星残骸のシミュレーションが成功し、データを解析することによって衝撃波と接触不連続面の間の平均距離や、逆行衝撃波と順行衝撃波の間の膨張速度プロファイルなどの観測量を説明するためには非一様な星間媒質を初期条件として設定する必要があることが明らかとなった。これらのことから研究は順調に成果を出しつつあると言える。
    まずは今年度の研究で得られた成果を査読付きの欧文論文として出版する。その後、本研究で得られる数値モデルをさらに一般的なものにするために、初期条件として非一様な星間媒質だけでなく、超新星爆発前の恒星活動(星風等)によってバブルが形成されているような場合についてのシミュレーションも行なっていく。さらに基礎方程式を磁気流体にすることで磁場の効果も取り入れてシンクロトロン放射の観測特性についても研究を行う。

    各研究計画班代表と事務局からなる総括班会議により策定して実行した.まず,パブリックアウトリーチの一環として,4月に東京・新宿・朝日カルチャーセンターにて「銀河系と太陽系の起源」全6回シリーズとして,本領域の計画研究代表者全員が市民講演会を行った.
    10月に計画研究A03班の研究代表者の生駒は,国際会議"From protoplanetary disks through planetary system architecture to planetary atmospheres and habitability"を沖縄にて主宰した.これは国内外から参加者約130名を集めたものであり,本新学術領域の研究者が多く参加し成果報告を幅広く行った.また,計画研究B03班の研究代表者の田村は,系外惑星及び星周円盤を中心とした直接撮像観測についての世界最大の国際国際会議"In the Spirit of Lyot 2019"を東京にて主催した.こちらも国内外から百名以上の参加があり,本新学術領域の研究者が多く参加し,成果報告を幅広く行った.研究分担者の小林らは名古屋大学にて研究会"Planet formation in Protoplanetary disks with magnetized disk winds"を開催し,本領域に関わる若手研究者に発表の機会を与えた. また,年度末に本領域全体の大研究会をオンラインで開催した.
    さらに,当初計画していたラボ・ローテーションとして複数名を別の研究拠点に派遣して共同研究を進めた.
    これまで通りTV会議システムを利用した「星惑星形成ゼミ」を毎月開催し,毎回10拠点以上から40名以上が参加している.新学術領域のホームページの拡張も進めた.星・惑星形成分野での世界最大の国際会議であるProtostars & Planetsの開催準備も進めている.
    2019年度末に,別の新学術領域「水惑星」とのジョイント会議を東京にて開催する予定だったが,コロカ禍が始まり,開催を断念した.代わりに,本領域のみの研究会を開催することで研究進捗状況の把握はできた.さらに,総括班メンバーが中心となって,二つの大きな国際会議を開催し,成功しているため,十分に研究が進んでいることが判断できた.
    現在はコロナ禍のため,対面式の研究集会の開催や国内外の研究者の派遣・招聘が困難である.また,本総括班活動の目玉の一つである,若手研究者のラボ・ローテーションの実行も困難である.そのため,オンライン形式の活動を最大限生かして研究活動を進めるように努める必要がある.2020年度中にその経験はかなり蓄積されたので,今後の研究の推進については順調にできると期待している.但し,観測機器を海外の観測所に移動させる計画については見通しが立っていないので,総括班としてどのようなサポートができるかを継続的検討する必要がある.

    千葉は、すばる望遠鏡の超広視野カメラならびにガイア衛星による観測データを詳細に解析して,銀河系の円盤とハローに新しい構造を発見し、星形成史と化学動力学に対して新しい知見が得られた.
    松本は2018年度に発表した周連星円盤の流体モデルに磁場を組み込み、大規模な数値シミュレーションを実施した.またこのシミュレーションでは同じく2018年度に開発したスキームBoris-HLLDを組み込んだ.さらに原始星収縮の問題にダストを組み込む研究に着手した.
    塚本は指導学生の高石と共同で,円盤の公転軸と中心星自転軸の進化を解明した.また,九大院生の古賀と共同でダストサイズ分布の磁気拡散への影響を解明した.さらに,PDの田中と形成初期段階での円盤におけるペブル降着による惑星形成を解明した.
    諏訪は,銀河への重元素の供給源である大質量星が起こす超新星爆発について研究を進めた.具体的には超新星爆発を駆動するニュートリノの輸送方程式を高次項まで取り入れた定式化を行い,またニュートリノ観測の理論予言や新しいデータ解析手法の開発を行った.
    長島は自身が構築した銀河形成モデルを用いて銀河の光度関数等の観測を再現するような星形成パラメータを調べ,銀河スケールで平均化した場合の星形成のタイムスケールについては,銀河系程度の銀河については約140~220 Myr程度であることを示した.
    研究代表者の犬塚は研究全体を統括した.2019年度は,フィラメント状分子雲が分裂して生まれる分子雲コアの角運動量の起源がフィラメント状分子雲に観測される亜音速の速度擾乱であることを突き止めた.これは分子雲コアから生まれる星や原始惑星系円盤の構造,特にその構造の差異の分布を理論的に理解することにつながるので重要である.
    コロナ禍のため,複数の研究拠点において十分に博士研究員を雇用できていないが,雇用した博士研究員や研究分担者らとおおむね順調に研究を進めている.
    これまで通り,課題達成に向けて研究を進める.雇用できなかった博士研究員を雇用してさらに研究を進める.

    本研究の目的は,太陽系近傍の銀河系円盤部の星形成論をさらに発展させ,銀河系の動的な進化の描像を確立することである.幾何学的に薄い銀河円盤の体積の大部分を占めるのは温度数千度程度の弱電離ガスであり,それは亜音速乱流状態にある.そのダイナミックスを駆動する大質量星による電離領域の膨張や超新星爆発による星間媒質の衝撃波圧縮作用では,低温高密度ガス雲形成過程のみならず,星間磁場増幅や高エネルギー宇宙線粒子加速・拡散も引き起こされる.本研究では銀河系の長い時間スケールにおける星形成活動と銀河進化を理解することを目的としている.
    既にこれまでの研究により,熱的不安定性に起因する多相構造が星間媒質の小スケールにまで埋め込まれているを我々は突き止めている.超新星残骸がこのような非一様な星間媒質中に伝搬することに伴い,百万年に一回の頻度で大規模衝撃波によって星間媒質は掃かれることになる.その結果,薄い銀河円盤空間の大部分を占めるウォームガス(WNM)の音速程度の乱流が常に駆動されており,乱流エネルギー密度はウォームガスの熱エネルギー密度程度になることが示唆される.また,ダイナモ理論の帰結として,磁場エネルギー密度がウォームガスと同程度になることが期待される.
    一方,繰り越しを行った経費により途中から博士研究員を雇用することができた.その研究員とは宇宙線圧力によって駆動される銀河風についての研究を開始している.これに関する先行研究によると,宇宙線圧力が卓越する場合は銀河風がよく吹くことが示されており,このことが銀河面内における宇宙線圧力の飽和値を決定している可能性が示唆された.
    以上をまとめると,つまり,ウォームガスの熱エネルギー密度と乱流エネルギー密度と磁場エネルギー密度と宇宙線のエネルギー密度が同じ程度の大きさになる理由を理解する端緒が得られたと考えている.
    宇宙線圧力の効果を入れた星間媒質の研究が遅れていたが,繰越した予算を用いて新たな博士研究員を雇用し,この方向の研究についての目途が立ってきた.
    繰り越した予算で雇用した博士研究員がこの科研費の研究に集中できない状況になったので,さらに新たに研究員を雇用して,研究を発展させることを目指す.

    現在の星形成研究において「なぜ,フィラメント状分子雲の幅が約0.1pc になるのか?」という問題に脚光が集まっているが,それに対する満足のいく解答はまだ無い.磁場の効果を考慮しない研究ではこれに反する答えが出るため,磁場の効果の重要性を多くの理論研究者が認識している.本研究員は,「磁場を含む分子雲の中でどのようにしてフィラメント状分子雲が形成されるのか?」という問題に理論・観測の両面から取り組み,フィラメントの幅を決める物理を研究した.特に大きな線密度のフィラメントの内部で磁場が乱れた乱流状態にあるかどうかを見極める.0.1pcの幅のフィラメントの成因を理解することで,星形成の開始条件を解明し,銀河円盤部における星形成過程の一般論を構築することを目指した.
    具体的な成果として,フィラメント状分子雲周辺の磁場構造を観測するプロジェクトに参画し,実際にハワイJCMTサブミリ波望遠鏡を用いて観測を進めた.この内容については,解析を進める予定であり,論文化を目指している.また,自身がプロポーザルを提案して受理された野辺山45m鏡を用いた観測結果についての解析をまとめ,論文として発表した.また,フィラメント状分子雲の分裂過程を統計的に記述する手法についても発展させ,分裂して生まれた分子雲コアの角運動量の分布がどのようになるかという点も共同研究を行った.
    また,この研究テーマに関連する研究について国際会議を開催した.これは名古屋大学にて開催したもので,参加者は約百名であり,海外からの参加者の方が日本人を上回る規模であった.この会議において,これまでの世界的研究をまとめ,今後の研究の方向性について議論を行った.
