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…
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…
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…
Distribution and evolution of Li abundance in red clump stars can be explained by the internal gravity waves
Xuefeng Li, Jianrong Shi, Yan Li +2
The study of Li phenomena in red clump (RC) stars can give us a deeper understanding of the structure and evolution of stars. \citet{2022ApJ...933...58C} explained the RC Li abunda…
Convective Mixing: The Formation Channel of Li-rich Giants
Xuefeng Li, Jianrong Shi, Yan Li +2
Increasing observed data indicate that part of giants has abnormally high lithium (Li) inside their surface, and their proportion is around 1%. Instead of pursuing the feasible mec…
The Pre-explosion Environments and The Progenitor of SN 2023ixf from the Hobby Eberly Telescope Dark Energy Experiment (HETDEX)
Chenxu Liu, Xinlei Chen, Xinzhong Er +20
Supernova (SN) 2023ixf was discovered on May 19th, 2023. The host galaxy, M101, was observed by the Hobby Eberly Telescope Dark Energy Experiment (HETDEX) collaboration over the pe…
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…
Planets Across Space and Time (PAST). II: Catalog and Analyses of the LAMOST-Gaia-Kepler Stellar Kinematic Properties
Di-Chang Chen, Jia-Yi Yang, Ji-Wei Xie +10
The Kepler telescope has discovered over 4,000 planets (candidates) by searching ? 200,000 stars over a wide range of distance (order of kpc) in our Galaxy. Characterizing the kine…
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…
