Ground-based Transit Observation of the Habitable-zone Super-Earth K2-3d
Akihiko Fukui, John Livingston, Norio Narita +4
We report the first ground-based transit observation of K2-3d, a 1.5 R_Earth planet supposedly within the habitable zone around a bright M-dwarf host star, using the Okayama 188 cm…
The K2-ESPRINT Project V: a short-period giant planet orbiting a subgiant star
Vincent Van Eylen, Simon Albrecht, Davide Gandolfi +31
We report on the discovery and characterization of the transiting planet K2-39b (EPIC 206247743b). With an orbital period of 4.6 days, it is the shortest-period planet orbiting a s…
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…
The K2-ESPRINT Project IV: A Hot Jupiter in a Prograde Orbit with a Possible Stellar Companion
Teruyuki Hirano, Grzegorz Nowak, Masayuki Kuzuhara +19
We report on the detection and early characterization of a hot Jupiter in a 3-day orbit around K2-34 (EPIC~212110888), a metal-rich F-type star located in the K2 Cycle 5 field. Our…
