Effects of global gas flows on type I migration
Masahiro Ogihara, Eiichiro Kokubo, Takeru K. Suzuki +2
Magnetically-driven disk winds would alter the surface density slope of gas in the inner region of a protoplanetary disk . This in turn affects planet form…
Formation of Close-in Super-Earths by Giant Impacts: Effects of Initial Eccentricities and Inclinations of Protoplanets
Yuji Matsumoto, Eiichiro Kokubo
Recent observations have revealed the eccentricity and inclination distributions of close-in super-Earths. These distributions have the potential to constrain their formation proce…
Dynamics of Porous Dust Aggregates and Gravitational Instability of Their Disk
Shugo Michikoshi, Eiichiro Kokubo
We consider the dynamics of porous icy dust aggregates in a turbulent gas disk and investigate the stability of the disk. We evaluate the random velocity of porous dust aggregates…
Simulating the Smallest Ring World of Chariklo
Shugo Michikoshi, Eiichiro Kokubo
A ring system consisting of two dense narrow rings has been discovered around Centaur Chariklo. The existence of these rings around a small object poses various questions, such as…
