Fundamental Parameters for Totally Eclipsing Contact Binaries Observed by TESS
Xu Ding, KaiFan Ji, ZhiMing Song +5
Totally eclipsing contact binaries provide a unique opportunity to accurately determine mass ratios through photometric methods alone, eliminating the need for spectroscopic data.…
Detection of Semidetached Eclipsing Binaries from TESS
Xu Ding, KaiFan Ji, QiYuan Cheng +4
Semidetached binaries, distinguished by their mass transfer phase, play a crucial role in elucidating the physics of mass transfer within interacting binary systems. To identify th…
Surface brightness-color relations for red giant branch stars using asteroseismic radii and Gaia distances (the ARD method)
Jianping Xiong, Qiyuan Cheng, Xiaodian Chen +4
Aims. Asteroseismic radius and Gaia distance (ARD) method has been proposed to establish the SBCRs for late-type stars. Methods. We select Kepler RGB stars with high-precision aste…
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…
