Carbon-Enhanced Metal-Poor Stars. III. Main-Sequence Turn-Off Stars from the SDSS/SEGUE Sample
Wako Aoki, Timothy C. Beers, Thirupathi Sivarani +6
The chemical compositions of seven Carbon-Enhanced Metal-Poor (CEMP) turn-off stars are determined from high-resolution spectroscopy. Five of them are selected from the SDSS/SEGUE…
The SEGUE Stellar Parameter Pipeline. III. Comparison with High-Resolution Spectroscopy of SDSS/SEGUE Field Stars
C. Allende Prieto, T. Sivarani, T. C. Beers +14
We report high-resolution spectroscopy of 125 field stars previously observed as part of the Sloan Digital Sky Survey and its program for Galactic studies, the Sloan Extension for…
Neutron-capture elements in the very metal-poor star HD88609: another st ar with excesses of light neutron-capture elements
Satoshi Honda, Wako Aoki, Yuhri Ishimaru +1
We obtained a high resolution, high signal-to-noise UV-blue spectrum of the extremely metal-poor red giant HD88609 to determine the abundances of heavy elements. Nineteen neutron-c…
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…
