The reason for the occurrence of W-type contact binaries
Jia Zhang, Sheng-Bang Qian, Li-Ying Zhu +1
For more than half a century, the puzzling W-type phenomenon in contact binaries has challenged astrophysicists. In these systems, the less massive component exhibits a higher surf…
The bimodal distribution of donor stars in X-ray binaries
Jia Zhang, Guo-Bao Zhang, Li-Ying Zhu +3
The classification of X-ray binaries into high- and low-mass types has historically lacked a unified, data-driven quantitative criterion, and large-scale statistical studies of the…
Observational properties of 155 O- and B-type massive pulsating stars
Xiang-dong Shi, Sheng-bang Qian, Li-ying Zhu +3
The O- and B-type (OB-type) pulsating stars are important objects to study the structure and evolution of massive stars through asteroseismology. A large amount of data from variou…
New pulsating stars detected in EA-type eclipsing binary systems based on TESS data
Xiang-Dong Shi, Sheng-Bang Qian, Lin-Jia Li
Pulsating stars in eclipsing binaries are very important to understand stellar interior structures through astroseismology because their absolute parameters such as the masses and…
