N-Body Simulation of Planetesimal Formation through Gravitational Instability of a Dust Layer in Laminar Gas Disk
Shugo Michikoshi, Eiichiro Kokubo, Shu-ichiro Inutsuka
We investigate the formation process of planetesimals from the dust layer by the gravitational instability in the gas disk using local -body simulations. The gas is modeled as a…
The dynamics of spiral arms in pure stellar disks
M. S. Fujii, J. Baba, T. R. Saitoh +3
It has been believed that spirals in pure stellar disks, especially the ones spontaneously formed, decay in several galactic rotations due to the increase of stellar velocity dispe…
Substellar Companions to Evolved Intermediate-Mass Stars: HD 145457 and HD 180314
Bun'ei Sato, Masashi Omiya, Yujuan Liu +15
We report the detections of two substellar companions orbiting around evolved intermediate-mass stars from precise Doppler measurements at Subaru Telescope and Okayama Astrophysica…
Formation of Terrestrial Planets from Protoplanets under a Realistic Accretion Condition
Eiichiro Kokubo, Hidenori Genda
The final stage of terrestrial planet formation is known as the giant impact stage where protoplanets collide with one another to form planets. So far this stage has been mainly in…
Gas Accretion onto a Protoplanet and Formation of a Gas Giant Planet
Masahiro N. Machida, Eiichiro Kokubo, Shu-ichiro Inutsuka +1
We investigate gas accretion onto a protoplanet, by considering the thermal effect of gas in three-dimensional hydrodynamical simulations, in which the wide region from a protoplan…
