Evidence for a companion to BM Gem, a silicate carbon star
Hideyuki Izumiura, Kunio Noguchi, Wako Aoki +12
Balmer and Paschen continuum emission as well as Balmer series lines of P Cygni-type profile from H_gamma through H_23 are revealed in the violet spectra of BM Gem, a carbon star a…
Non-LTE line formation for heavy elements in four very metal-poor stars
L. Mashonkina, G. Zhao, T. Gehren +6
Stellar parameters and abundances of Na, Mg, Al, K, Ca, Sr, Ba, and Eu are determined for four very metal-poor stars (-2.66 < [Fe/H] < -2.15) based on non-LTE line formation and an…
A Substellar Companion to the Intermediate-Mass Giant 11 Com
Y. J. Liu, Bun'ei Sato, G. Zhao +16
We report the detection of a substellar companion orbiting the intermediate-mass giant star 11 Com (G8 III). Precise Doppler measurements of the star from Xinglong station and Okay…
Current Performance and On-Going Improvements of the 8.2 m Subaru Telescope
Masanori Iye, Hiroshi Karoji, Hiroyasu Ando +2
An overview of the current status of the 8.2 m Subaru Telescope constructed and operated at Mauna Kea, Hawaii, by the National Astronomical Observatory of Japan is presented. The b…
Spectroscopic Studies of Extremely Metal-Poor Stars with Subaru/HDS:I. Observational Data
S. Honda, W. Aoki, H. Ando +14
We have obtained high-resolution (R 50,000 or 90,000), high-quality (S/N $\ga$ 100) spectra of 22 very metal-poor stars ([Fe/H] $\la$ -2.5) with the High Dispersion Spectr…
Chemical composition of carbon-rich, very metal-poor subgiant LP625-44 observed with the Subaru/HDS
W. Aoki, H. Ando, S. Honda +14
We have obtained a high resolution (R~90,000) spectrum of the carbon- and s-process-element-rich, very metal-poor ([Fe/H]=-2.7) subgiant LP625-44, as well as that of HD140283 (a me…
