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…
Lithium in Wide Binaries: Effective Temperature Governs Depletion while Rotation Plays a Minor Role
Cheng-Cheng Xie, Hai-Jun Tian, Jian-Rong Shi +1
Using a sample of 116 wide binary systems as coeval and chemically homogeneous stellar pairs, we investigate the factors governing lithium depletion in main-sequence stars. We reco…
Revisiting the Li abundances of Stars with and without Detected Planets from the High Resolution Spectroscopy
Jinxiao Qin, Hong-Liang Yan, Wenyuan Cui +12
Whether the presence of planets affects the lithium (Li) abundance of their host stars is still an open question. To investigate the difference of the Li abundance between planet-h…
Lithium Abundances from the LAMOST Med-Resolution Survey Data Release 9
Ming-Yi Ding, Jian-Rong Shi, Hong-liang Yan +9
Lithium is a fragile but crucial chemical element in the universe, exhibits interesting and complex behaviors. Thanks to the massive spectroscopic data from the Large Sky Area Mult…
LTD064402+245919: A Subgiant with a 1-3 M Undetected Companion Identified from LAMOST-TD Data
Fan Yang, Bo Zhang, Richard J. Long +11
Single-line spectroscopic binaries recently contribute to the stellar-mass black hole discovery, independently of the X-ray transient method. We report the identification of a sing…
LAMOST/HRS Spectroscopic Analysis of Two New Li-rich Giants
Zeming Zhou, Jianrong Shi, Hongliang Yan +9
Two Li-rich candidates, TYC 1338-1410-1 and TYC 2825-596-1, were observed with the new high-resolution echelle spectrograph, LAMOST/HRS. Based on the high-resolution and high-signa…
The nature of the Li enrichment in the most Li-rich giant star
Hong-Liang Yan, Jian-Rong Shi, Yu-Tao Zhou +13
About one percent of giants\upcite{Brown1989} are detected to have anomalously high lithium (Li) abundances in their atmospheres, conflicting directly with the prediction of the st…
NLTE analysis of copper lines in different stellar populations
J. R. Shi, H. L. Yan, Z. M. Zhou +1
The copper abundances of 29 metal-poor stars are determined based on the high resolution, high signal-to-noise ratio spectra from the UVES spectragraph at the ESO VLT telescope. Ou…
