Regular Radial Velocity Variations in Nine G- and K-type Giant Stars: Eight Planets and One Planet Candidate
Huan-Yu Teng, Bun'ei Sato, Takuya Takarada +9
We report the detection of radial velocity variations in nine evolved G- and K-type giant stars. The observations were conducted at Okayama Astrophysical Observatory. Planets or pl…
Elemental abundances of nearby M dwarfs based on high-resolution near-infrared spectra obtained by the Subaru/IRD survey: Proof of concept
Hiroyuki Tako Ishikawa, Wako Aoki, Teruyuki Hirano +24
Detailed chemical analyses of M dwarfs are scarce but necessary to constrain the formation environment and internal structure of planets being found around them. We present element…
Early Initiation of Inner Solar System Formation at Dead-Zone Inner Edge
Takahiro Ueda, Masahiro Ogihara, Eiichiro Kokubo +1
The inner solar system possesses a unique orbital structure in which there are no planets inside the Mercury orbit and the mass is concentrated around the Venus and Earth orbits. T…
Size evolution of close-in super-Earths through giant impacts and photoevaporation
Yuji Matsumoto, Eiichiro Kokubo, Pin-Gao Gu +1
The Kepler transit survey with follow-up spectroscopic observations has discovered numerous super-Earth sized planets and revealed intriguing features of their sizes, orbital perio…
Merging Criteria for Planetesimal Collisions
Takashi Shibata, Eiichiro Kokubo, Natsuki Hosono
In the standard scenario of planet formation, terrestrial planets, ice giants, and cores of gas giants are formed by the accumulation of planetesimals. However, there are few N-bod…
Planetesimal Dynamics in the Presence of a Giant Planet
Kangrou Guo, Eiichiro Kokubo
Standard models of planet formation explain how planets form in axisymmetric, unperturbed disks in single star systems. However, it is possible that giant planets could have alread…
