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…
Solar rotation inferred from radial velocities of the sun-as-a-star during the 2012 May 21 eclipse
Yoichi Takeda, Osamu Ohshima, Eiji Kambe +6
With an aim to examine how much information of solar rotation can be obtained purely spectroscopically by observing the sun-as-a-star during the 2012 May 21 eclipse at Okayama Astr…
Detection of solar-like oscillations in the bright red giant stars Psc and Tau from a 190-day high-precision spectroscopic multisite campaign
P. G. Beck, E. Kambe, M. Hillen +35
Red giants are evolved stars which exhibit solar-like oscillations. Although a multitude of stars have been observed with space telescopes, only a handful of red-giant stars were t…
MITSuME--Multicolor Imaging Telescopes for Survey and Monstrous Explosions
T. Kotani, N. Kawai, K. Yanagisawa +25
Development of MITSuME is reported. Two 50-cm optical telescopes have been built at Akeno in Yamanashi prefecture and at Okayama Astrophysical Observatory (OAO) in Okayama prefectu…
Photospheric Abundances of Volatile and Refractory Elements in Planet-Harboring Stars
Y. Takeda, B. Sato, E. Kambe +16
By using the high-dispersion spectra of 14 bright planet-harboring stars (along with 4 reference stars) observed with the new coude echelle spectrograph at Okayama Astrophysical Ob…
