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…

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…
