Identifying Hierarchically Triple Star Systems with Gaia DR3 and LAMOST
Tongyu He, Jiao Li, Jiangdan Li +8
Triple star systems are critical for understanding stellar dynamics and compact objects in astrophysics, yet confirmed hierarchical triples identified via spectroscopy remain limit…
The First Photometric Analysis of Two Low Mass Ratio Contact Binary Systems In TESS Survey
Qiyuan Cheng, Jianping XIong, Xu Ding +8
Low mass-ratio (q) contact binary systems are progenitors of stellar mergers such as blue straggles (BS) or fast-rotating FK Com stars. In this study, we present the first light cu…
Derivative Spectroscopy and its Application at Detecting the Weak Emission/Absorption Lines
Lihuan Yu, Jiangdan Li, Jinliang Wang +4
The development of spectroscopic survey telescopes like Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST), Apache Point Observatory Galactic Evolution Experiment a…
TYC 3340-2437-1: A Quadruple System with A Massive Star
Jiao Li, Chao Liu, Changqing Luo +10
Hierarchical massive quadruple systems are ideal laboratories for examining the theories of star formation, dynamical evolution, and stellar evolution. The successive mergers of hi…
A new route to massive hot subdwarfs: common envelope ejection from asymptotic giant branch stars
Zhenwei Li, Yangyang Zhang, Hailiang Chen +5
The hot subdwarf O/B stars (sdO/Bs) are known as extreme horizontal branch stars, which is of great importance in stellar evolution theory. The sdO/Bs are generally thought to have…
