Sodium Absorption Systems toward SN Ia 2014J Originate on Interstellar Scales
K. Maeda, A. Tajitsu, K. S. Kawabata +21
Na I D absorbing systems toward Type Ia supernovae (SNe Ia) have been intensively studied over the last decade with the aim of finding circumstellar material (CSM), which is an ind…
Five New Exoplanets Orbiting Three Metal-Rich, Massive Stars: Two-Planet Systems Including Long-Period Planets, and an Eccentric Planet
Hiroki Harakawa, Bun'ei Sato, Masashi Omiya +13
We report detections of new exoplanets from a radial velocity (RV) survey of metal-rich FGK stars by using three telescopes. By optimizing our RV analysis method to long time-basel…
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…
