Secular Gravitational Instability of a Dust Layer in Shear Turbulence
Shugo Michikoshi, Eiichiro Kokubo, Shu-ichiro Inutsuka
We perform a linear stability analysis of a dust layer in a turbulent gas disk. Youdin (2011) investigated the secular gravitational instability of a dust layer using hydrodynamic…
A Possible Substellar Companion to the Intermediate-mass Giant HD 175679
Liang Wang, Bun'ei Sato, Gang Zhao +12
We report the discovery of a substellar companion around the intermediatemass giant HD 175679. Precise radial velocity data of the star from Xinglong Station and Okayama Astrophysi…
Merging Criteria for Giant Impacts of Protoplanets
H. Genda, E. Kokubo, S. Ida
At the final stage of terrestrial planet formation, known as the giant impact stage, a few tens of Mars-sized protoplanets collide with one another to form terrestrial planets. Alm…
Formation of a Propeller Structure by a Moonlet in a Dense Planetary Ring
Shugo Michikoshi, Eiichiro Kokubo
The Cassini spacecraft discovered a propeller-shaped structure in Saturn's A ring. This propeller structure is thought to be formed by gravitational scattering of ring particles by…
