Detection of a Planetary Companion around the giant star \gam1leo
Inwoo Han, B. C. Lee, K. M. Kim +3
Aims: Our primary goal is to search for planets around intermediate mass stars. We are also interested in studying the nature of radial velocity (RV) variations of K giant stars. M…
The Lorentz force in atmospheres of CP stars: 56 Arietis
D. Shulyak, O. Kochukhov, G. Valyavin +5
The presence of electric currents in the atmospheres of magnetic chemically peculiar (mCP) stars could bring important theoretical constrains about the nature and evolution of magn…
Atlas of Vega: 3850 -- 6860 Å
Hyun-Sook Kim, Inwoo Han, G. Valyavin +3
We present a high resolving power ( / = 90,000) and high signal-to-noise ratio (700) spectral atlas of Vega covering the 3850 -- 6860 Åwavelength range. The atlas is…
Can Sodium Abundances of A-Type Stars Be Reliably Determined from Na I 5890/5896 Lines?
Yoichi Takeda, Dong-Il Kang, Inwoo Han +2
An extensive non-LTE abundance analysis based on Na I 5890/5896 doublet lines was carried out for a large unbiased sample of ~120 A-type main-sequence stars (including 23 Hyades st…
A Massive Substellar Companion to the Massive Giant HD 119445
Masashi Omiya, Hideyuki Izumiura, Inwoo Han +10
We detected a brown dwarf-mass companion around the intermediate-mass giant star HD 119445 (G6III) using the Doppler technique. This discovery is the first result from a Korean-Jap…
