A Systematic NLTE Study of Very Metal-Poor Stars with Metallicity Down to dex. II. Lithium Abundance and New Insight to the Lithium Plateau
Hong-Liang Yan, Jinxiao Qin, Shuai Liu +12
Metal-poor stars are crucially important for understanding the early Galaxy, first stars, and the Universe. In this series of papers, we present a homogeneous non-local thermodynam…
Unevolved Li-rich stars at low metallicity: a possible formation pathway through novae
Tadafumi Matsuno, Alex Kemp, Ataru Tanikawa +7
A small fraction of low-mass stars have been found to have anomalously high Li abundances. Although it has been suggested that mixing during the red giant branch phase can lead to…
NLTE analysis for Y I and Y II in atmospheres of F-G-K stars
Sofya Alexeeva, Yu Wang, Gang Zhao +5
The non-local thermodynamical equilibrium (NLTE) line formation of Y I and Y II is considered in 1D LTE model atmospheres of F-G-K-type stars. The model atom was constructed with t…
Non-LTE analysis of neutral copper in the late-type metal-poor stars
H. L. Yan, J. R. Shi, G. Zhao
We investigated the copper abundances for late-type stars in the Galactic disk and halo with effective temperatures from K to K and [Fe/H] from to $-0.17…
