Carbon in J0815+4729: Casting A Shadow of Doubt on the Interpretation of CH Absorption in the Most Primitive Stars
Junbo Zhang, Carlos Allende Prieto, Yeisson Osorio +7
We revisit the carbon abundance in the primitive iron-poor star J0815+4729 ([Fe/H] 5.49). J0815+4729 is so carbon-enhanced and oxygen-rich that, in addition to CH and C$_{2}…
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…
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…
The Mini-SiTian Array: first-two-year operation
Min He, Hong Wu, Liang Ge +70
The SiTian project, designed to utilize 60 telescopes distributed across multiple sites in China, is a next-generation time-domain survey initiative. As a pathfinder for the SiTian…
Discovery of an Extremely r-process-enhanced Thin-disk Star with [Eu/H] = +0.78
Xiao-Jin Xie, Jianrong Shi, Hong-Liang Yan +9
Highly r-process-enhanced stars are rare and usually metal-poor ([Fe/H] < - 1.0), and mainly populate the Milky Way halo and dwarf galaxies. This study presents the discovery of a…
