Shock-Generating Planetesimals Perturbed by a Giant Planet in a Gas Disk

M. Nagasawa, K. K. Tanaka, H. Tanaka +3

We examined the excitations of planetesimals caused by the resonances of a giant planet in a protoplanetary gas disk. The highly excited planetesimals generate bow shocks, the mech…

Planets around the evolved stars 24 Booties and $γ$ 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…
