The K2-ESPRINT Project III: A Close-in Super-Earth around a Metal-rich Mid-M Dwarf
Teruyuki Hirano, Akihiko Fukui, Andrew W. Mann +18
We validate a planet on a close-in orbit ( days) around K2-28 (EPIC 206318379), a metal-rich M4-type dwarf in the Campaign 3 fiel…
Characterization of the K2-19 Multiple-Transiting Planetary System via High-Dispersion Spectroscopy, AO Imaging, and Transit Timing Variations
Norio Narita, Teruyuki Hirano, Akihiko Fukui +16
K2-19 (EPIC201505350) is an interesting planetary system in which two transiting planets with radii ~ 7 (inner planet b) and ~ 4 (outer planet c) have orbit…
A low stellar obliquity for WASP-47, a compact multiplanet system with a hot Jupiter and an ultra-short period planet
Roberto Sanchis-Ojeda, Joshua N. Winn, Fei Dai +9
We have detected the Rossiter-Mclaughlin effect during a transit of WASP-47b, the only known hot Jupiter with close planetary companions. By combining our spectroscopic observation…
The K2-ESPRINT Project. I. Discovery of the Disintegrating Rocky Planet K2-22b with a Cometary Head and Leading Tail
R. Sanchis-Ojeda, S. Rappaport, E. Pallé +28
We present the discovery of a transiting exoplanet candidate in the K2 Field-1 with an orbital period of 9.1457 hr: K2-22b. The highly variable transit depths, ranging from 0…
Precise Radial Velocity Measurements for Kepler Giants Hosting Planetary Candidates: Kepler-91 and KOI-1894
Bun'ei Sato, Teruyuki Hirano, Masashi Omiya +6
We present results of radial-velocity follow-up observations for the two Kepler evolved stars Kepler-91 (KOI-2133) and KOI-1894, which had been announced as candidates to host tran…
