Self-consistent Stellar Radial Velocities from LAMOST Medium-Resolution Survey (MRS) DR7
Bo Zhang, Jiao Li, Fan Yang +12
Radial velocity (RV) is among the most fundamental physical quantities obtainable from stellar spectra and is rather important in the analysis of time-domain phenomena. The LAMOST…
LAMOST/HRS Spectroscopic Analysis of Two New Li-rich Giants
Zeming Zhou, Jianrong Shi, Hongliang Yan +9
Two Li-rich candidates, TYC 1338-1410-1 and TYC 2825-596-1, were observed with the new high-resolution echelle spectrograph, LAMOST/HRS. Based on the high-resolution and high-signa…
Most Lithium-rich Low-mass Evolved Stars Revealed as Red Clump stars by Asteroseismology and Spectroscopy
Hong-Liang Yan, Yu-Tao Zhou, Xianfei Zhang +19
Lithium has confused scientists for decades at almost each scale of the universe. Lithium-rich giants are peculiar stars with lithium abundances over model prediction. A large frac…
KIC 12268220: A Scuti Pulsating Star and an Active Protohelium White Dwarf in an Eclipsing Binary System
Kaiming Cui, Zhao Guo, Qing Gao +4
We present a photometric, spectroscopic, asteroseismic, and evolutionary analysis of the Algol-type eclipsing binary KIC 12268220. We find the O'Connell effect and anticorrelated e…
Lithium-rich Giants in LAMOST Survey. I. The Catalog
Qi Gao, Jian-Rong Shi, Hong-Liang Yan +5
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…
Correlation between the ionizing continuum and variable C iv broad absorption line in multi-epoch observations of SDSS J141007.74+541203.3
Hong-Yan Huang, Cai-Juan Pan, Wei-Jian Lu +9
Correlation between the variations of quasar absorption lines and the ionizing continuum have been recently confirmed in systematic studies. However, no convincing individual case…
