Planetesimal Formation by Gravitational Instability of a Porous-Dust Disk
Shugo Michikoshi, Eiichiro Kokubo
Recently it is proposed that porous icy dust aggregates are formed by pairwise accretion of dust aggregates beyond the snowline. We calculate the equilibrium random velocity of por…
High-Contrast Imaging of Intermediate-Mass Giants with Long-Term Radial Velocity Trends
Tsuguru Ryu, Bun'ei Sato, Masayuki Kuzuhara +62
A radial velocity (RV) survey for intermediate-mass giants has been operated for over a decade at Okayama Astrophysical Observatory (OAO). The OAO survey has revealed that some gia…
A Pair of Giant Planets around the Evolved Intermediate-Mass Star HD 47366: Multiple Circular Orbits or a Mutually Retrograde Configuration
Bun'ei Sato, Liang Wang, Yu-Juan Liu +19
We report the detection of a double planetary system around the evolved intermediate-mass star HD 47366 from precise radial-velocity measurements at Okayama Astrophysical Observato…
