A Young Brown Dwarf Companion to DH Tauri

Yoichi Itoh, Masahiko Hayashi, Motohide Tamura +20

We present the detection of a young brown dwarf companion DH Tau B associated with the classical T Tauri star DH Tau. Near-infrared coronagraphic observations with CIAO on the Suba…

A Strong Lyman-alpha Emitter at z=6.33 in the Subaru Deep Field Selected as an i' Dropout

T. Nagao, Y. Taniguchi, N. Kashikawa +37

We report on the discovery of a star-forming galaxy at z=6.33 in the Subaru Deep Field. This object is selected as a candidate of an i'-dropout, high-redshift galaxy around z=6 bec…

Oxygen Overabundance in the Extremely Iron-Poor Star CS29498-043

Wako Aoki, John E. Norris, Sean G. Ryan +4

An abundance analysis for the carbon-enhanced, extremely iron-poor ([Fe/H] -3.5) star CS29498-043 has been obtained using new high-resolution, high signal-to-noise spectra from the…

Spectroscopic Studies of Extremly Metal-Poor Stars with Subaru/HDS:II.The r-process Elements, Including Thorium

S. Honda, W. Aoki, T. Kajino +5

We present the abundance analyses for the neutron-capture elements, and discuss the observed abundance distributions in very metal-poor stars with excesses of r-process elements. A…

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…
