Identify ~20,000 Li-rich Giants in the LAMOST Low-Resolution Survey
Ming-Yi Ding, Liang Wang, Jian-Rong Shi +8
Li-rich giants serve as valuable tracers of stellar evolution and surface enrichment processes, for which a statistically large and homogeneous sample is crucial. Using the massive…
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…
Meridional Circulation. I. A Formation Channel for Lithium-rich and Super Lithium-rich Red Clump Stars
Xue-Feng Li, Jian-Rong Shi, Yan Li +2
Current observations indicate that stars with higher rotation rates appear to maintain more surface lithium, and the majority of lithium-rich giants are indeed red clump stars. Hen…
LAMA: LAMOST Medium-Resolution Spectral Analysis Pipeline
Chun-qian Li, Jian-rong Shi, Hong-liang Yan +3
The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) has obtained more than 23 million spectra, opening an unprecedented opportunity to study stellar physics, as…
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…
Reconstructing Intrinsic Stellar Noise with Stellar Atmospheric Parameters and Chromospheric Activity
Jinghua Zhang, Maosheng Xiang, Jie Yu +9
Accurately characterizing intrinsic stellar photometric noise induced by stellar astrophysics, such as stellar activity, granulation, and oscillations, is of crucial importance for…
