Carbon Enhanced Metal-Poor Stars. I. Chemical Compositions of 26 Stars
Wako Aoki, Timothy C. Beers, Norbert Christlieb +3
The chemical compositions of 26 metal-poor stars that exhibit strong CH and/or C2 molecular bands are determined based on high-resolution spectroscopy. We define carbon-enhanced st…
A high-resolution spectral analysis of three carbon-enhanced metal-poor stars
Aruna Goswami, Wako Aoki, Timothy C. Beers +4
We present results of an analysis of high-resolution spectra obtained with the Subaru Telescope High Dispersion Spectrograph, of two Carbon-Enhanced Metal-Poor stars, HE 1305+0007…
Detection of Diffuse Interstellar Bands in the z=0.5 Damped Lyman alpha system towards AO 0235+164
Brian A. York, Sara L. Ellison, Brandon Lawton +4
We report the first detection of the 5705 and 5780 A Diffuse Interstellar Bands (DIBs) in a moderate redshift Damped Lyman alpha (DLA) system. We measure a rest frame equivalent wi…
Neutron-capture elements in the very metal-poor star HD122563
S. Honda, W. Aoki, Y. Ishimaru +2
We obtained high resolution, high S/N spectroscopy for the very metal-poor star HD122563 with the Subaru Telescope High Dispersion Spectrograph. Previous studies have shown that th…
