Planets around the evolved stars 24 Booties and Libra: A 30d-period planet and a double giant-planet system in possible 7:3 MMR
Takuya Takarada, Bun'ei Sato, Masashi Omiya +10
We report the detection of planets around two evolved giant stars from radial velocity measurements at Okayama Astrophysical observatory. 24 Boo (G3IV) has a mass of $0.99\,M_{\odo…
Formation of the terrestrial planets in the solar system around 1 au via radial concentration of planetesimals
Masahiro Ogihara, Eiichiro Kokubo, Takeru K. Suzuki +1
No planets exist inside the orbit of Mercury and the terrestrial planets of the solar system exhibit a localized configuration. According to thermal structure calculation of protop…
Formation of close-in super-Earths in evolving protoplanetary disks due to disk winds
Masahiro Ogihara, Eiichiro Kokubo, Takeru K. Suzuki +1
Planets with masses larger than about 0.1 Earth-masses undergo rapid inward migration (type I migration) in a standard protoplanetary disk. Recent magnetohydrodynamical simulations…
Gravitational instability of a dust layer composed of porous silicate dust aggregates in a protoplanetary disk
Misako Tatsuuma, Shugo Michikoshi, Eiichiro Kokubo
Planetesimal formation is one of the most important unsolved problems in planet formation theory. In particular, rocky planetesimal formation is difficult because silicate dust gra…
