Probabilistic Stellar Age Estimation for Gaia XP Stars with NGBoost
Xiaokun Hou, Wenbo Wu, Gang Zhao +2
Stellar age is a fundamental quantity for Galactic archaeology, but reliable age estimation for large stellar samples remains challenging. In this work, we develop an uncertainty a…
A Catalog of 486 Barium Stars Identified in GALAH DR4
Guochao Yang, Jingkun Zhao, Nian Liu +4
We present a catalog of 486 Ba stars identified in the GALAH DR4 survey using high-resolution spectra and precise abundance measurements. The sample was selected based on s-process…
HR-GO II: chemical abundances of low- retrograde dynamically-tagged-groups: Revealing Thamnos as a very metal-poor substructure
Renjing Xie, Zhen Yuan, Haining Li +12
Milky Way halo substructures identified in dynamical space are known to suffer from contamination from the Milky Way in-situ stars, which makes their accreted origins uncertain. We…
Chasing the formation history of the Galactic metal-poor disc
Xiaokun Hou, Ruizhi Zhang, Haining Li +1
In our previous work, we identified metal-poor stars ([Fe/H] -1.0) from the LAMOST Survey. This work estimates their chemical abundances and explores the origin a…
A Modified Initial Mass Function of the First Stars with Explodability Theory under Different Enrichment Scenarios
Ruizheng Jiang, Gang Zhao, Haining Li +1
The most metal-poor stars record the earliest metal enrichment triggered by Population III stars. By comparing observed abundance patterns with theoretical yields of metal-free sta…
The puzzling abundance pattern of HD134439 and HD134440
Y. Q. Chen, G. Zhao
Abundances of 18 elements are determined for the common proper-motion pair, HD134439 and HD134440, which shows high [Mn/Fe] and low [α/Fe] ratios as compared to normal halo stars.…
