Chemical analysis of very metal-poor turn-off stars from SDSS-DR12
P. François, E. Caffau, S. Wanajo +7
The most metal-poor stars are the relics of the early chemical evolution of the Galaxy. Their chemical composition is an important tool to constrain the nucleosynthesis in the firs…
Tracing the origin of moving groups I. The γ Leo moving group with high resolution spectra from the Subaru Telescope
Xilong Liang, Jingkun Zhao, Gang Zhao +7
We present chemical abundances of 15 stars in the γ Leo moving group based on high-resolution spectra with the Subaru High Dispersion Spectrograph. The sample was picked up by appl…
LAMOST J2217+2104: a new member of carbon-enhanced extremely metal-poor stars with excesses of Mg and Si
Wako Aoki, Tadafumi Matsuno, Satoshi Honda +4
We report on the elemental abundances of the carbon-enhanced metal-poor (CEMP) star J2217+2104 discovered by our metal-poor star survey with LAMOST and Subaru. This object is a red…
Optical high-resolution spectroscopy of 14 young -rich stars
Tadafumi Matsuno, David Yong, Wako Aoki +1
We report chemical abundances of 14 young -rich stars including neutron-capture elements based on high-quality optical spectra from HIRES/Keck I and differential line-by-line an…
