Chemical Abundance Analysis of the Extremely Metal-Poor Star HE 1300+0157
Anna Frebel, John E. Norris, Wako Aoki +5
We present a detailed chemical abundance analysis of HE 1300+0157, a subgiant with [Fe/H]=-3.9. From a high-resolution, high-S/N Subaru/HDS spectrum we find the star to be enriched…
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…
Neutron-capture elements in the metal-poor globular cluster M15
Kaori Otsuki, Satoshi Honda, Wako Aoki +2
We report on observations of six giants in the globular cluster M15 (NGC 7078) using the Subaru Telescope to measure neutron-capture elemental abundances. Our abundance analyses ba…
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…
