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…
New Symbiotic Stars from LAMOST DR10 Spectra and Multi-band Photometry
Jing Chen, Liang Wang, Yin-Bi Li +5
Symbiotic star (SySt) is long-period interacting binary system, typically consisting of a white dwarf and a red giant surrounded by a nebula. These systems are natural astrophysica…
The Impact of Fiber Cross Contamination on Radial Velocity Precision
Chenyang Ji, Sharon Xuesong Wang, Kai Zhang +1
High-resolution spectrographs with precise radial velocity (PRV) capabilities require careful considerations in instrumental design and data processing in order to reach the 10 cm/…
Identifying eclipsing binary stars with TESS data based on a new hybrid deep learning model
Ying Shan, Jing Chen, Zichong Zhang +3
Eclipsing binary systems (EBs), as foundational objects in stellar astrophysics, have garnered significant attention in recent years. These systems exhibit periodic decreases in li…
A photometric and spectroscopic study of eight semi-detached eclipsing binaries
Yajuan Lei, Guiping Zhou, Liang Wang +3
By cross-matching the eclipsing binary catalog from TESS with that from LAMOST MRS, semi-detached eclipsing binaries with radial velocities coverage spanning more than 0.3 phases w…
