LAMOST YSOs. I. Spectroscopically identifying and characterizing M-type young stellar objects
Xiang-Song Fang, Jian-Rong Shi, Ming-Yi Ding +1
This study utilized LAMOST low-resolution spectra to identify M-type YSOs and characterize their accretion signatures. We measured characteristic features, including hydrogen Balme…
The temporal and spatial variations of lithium abundance in the Galactic disc
Tiancheng Sun, Shaolan Bi, Xunzhou Chen +7
This study investigates the temporal and spatial variations in lithium abundance within the Milky Way using a sample of 22,034 main-sequence turn-off (MSTO) stars and subgiants, ch…
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…
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…
Stellar Atmospheric Parameters of M-type Stars from LAMOST DR8
Ming-Yi Ding, Jian-Rong Shi, Yue Wu +9
The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) Low Resolution Spectroscopic Survey (LRS) provides massive spectroscopic data of M-type stars, and the derive…
The Lithium Abundances from the Large Sky Area Multi-object Fiber Spectroscopic Telescope Medium-resolution Survey. I. The Method
Qi Gao, Jian-Rong Shi, Hong-Liang Yan +9
Standard stellar evolution model predicts a severe depletion of lithium (Li) abundance during the first dredge-up process (FDU). Yet a small fraction of giant stars are still found…
