Spectroscopic ages for 4 million main-sequence dwarf stars from LAMOST DR10 estimated with data-driven approach
Jia-Hui Wang, Maosheng Xiang, Meng Zhang +5
Stellar age determination for large samples of stars opens new avenues for a broad range of astronomical sciences. While precise stellar ages for evolved stars have been derived fr…
Homogeneous Stellar Atmospheric Parameters and 22 Elemental Abundances for FGK Stars Derived From LAMOST Low-resolution Spectra with DD-Payne
Meng Zhang, Maosheng Xiang, Yuan-Sen Ting +11
A deep understanding of our Galaxy desires detailed decomposition of its stellar populations via their chemical fingerprints. This requires precise stellar abundances of many eleme…
Metallicities of 20 Million Giant Stars Based on Gaia XP spectra
Lin Yang, Haibo Yuan, Bowen Huang +8
We design an uncertainty-aware cost-sensitive neural network (UA-CSNet) to estimate metallicities from dereddened and corrected Gaia BP/RP (XP) spectra for giant stars. This method…
Ba-enhanced dwarf and subgiant stars in the LAMOST Galactic surveys
Meng Zhang, Maosheng Xiang, Hua-Wei Zhang +3
Ba-enhanced stars are interesting probes of stellar astrophysics and Galactic formation history. In this work, we investigate the chemistry and kinematics for a large sample of Ba-…
Chemically peculiar A and F stars with enhanced s-process and iron-peak elements: stellar radiative acceleration at work
Maosheng Xiang, Hans-Walter Rix, Yuan-Sen Ting +6
We present metal-rich (dex) A and F stars whose surface abundances deviate strongly from Solar abundance ratios and cannot plausibly reflect the…
A Catalog of RV Variable Star Candidates from LAMOST
Zhijia Tian, Xiaowei Liu, Haibo Yuan +14
RV variable stars are important in astrophysics. The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) spectroscopic survey has provided ~ 6.5 million stellar spec…
