A Double Planetary System around the Evolved Intermediate-Mass Star HD 4732
Bun'ei Sato, Masashi Omiya, Robert A. Wittenmyer +10
We report the detection of a double planetary system orbiting around the evolved intermediate-mass star HD 4732 from precise Doppler measurements at Okayama Astrophysical Observato…
A Common Proper Motion Stellar Companion to HAT-P-7
Norio Narita, Yasuhiro H. Takahashi, Masayuki Kuzuhara +51
We report that HAT-P-7 has a common proper motion stellar companion. The companion is located at arcsec to the east and estimated as an M5.5V dwarf based on its colors. W…
Effects of Dynamical Evolution of Giant Planets on Survival of Terrestrial Planets
Soko Matsumura, Shigeru Ida, Makiko Nagasawa
The orbital distributions of currently observed extrasolar giant planets allow marginally stable orbits for hypothetical, terrestrial planets. In this paper, we propose that many o…
The Orbital Stability of Planets Trapped in the First-Order Mean-Motion Resonances
Yuji Matsumoto, Makiko Nagasawa, Shigeru Ida
Many extrasolar planetary systems containing multiple super-Earths have been discovered. N-body simulations taking into account standard type-I planetary migration suggest that pro…
