Evolution of the Angular Momentum of Molecular Cloud Cores in Magnetized Molecular Filaments
Yoshiaki Misugi, Shu-ichiro Inutsuka, Doris Arzoumanian +1
The angular momentum of molecular cloud cores plays a key role in the star formation process. However, the evolution of the angular momentum of molecular cloud cores formed in magn…
Growth of Massive Molecular Cloud Filament by Accretion Flows I: Slow Shock Instability v.s. Ambipolar Diffusion
Daisei Abe, Tsuyoshi Inoue, Shu-ichiro Inutsuka
The Herschel Gould Belt Survey showed that stars form in dense filaments in nearby molecular clouds. Recent studies suggest that massive filaments are bound by the slow shocks caus…
An improved dynamical Poisson equation solver for self-gravity
Ryunosuke Maeda, Tsuyoshi Inoue, Shu-ichiro Inutsuka
Since self-gravity is crucial in the structure formation of the universe, many hydrodynamics simulations with the effect of self-gravity have been conducted. The multigrid method i…
Giant Impact Events for Protoplanets: Energetics of Atmospheric Erosion by Head-on Collision
Kenji Kurosaki, Shu-ichiro Inutsuka
Numerous exoplanets with masses ranging from Earth to Neptune and radii larger than Earth have been found through observations. These planets possess atmospheres that range in mass…
Triple spiral arms of a triple protostar system imaged in molecular lines
Jeong-Eun Lee, Tomoaki Matsumoto, Hyun-Jeong Kim +9
Most stars form in multiple star systems. For a better understanding of their formation processes, it is important to resolve the individual protostellar components and the surroun…
The History of The Milky Way: The Evolution of Star Formation, Cosmic Rays, Metallicity, and Stellar Dynamics over Cosmic Time
Jiro Shimoda, Shu-ichiro Inutsuka, Masahiro Nagashima
We study the long-term evolution of the Milky Way (MW) over cosmic time by modeling the star formation, cosmic rays, metallicity, stellar dynamics, outflows and inflows of the gala…
