KIC 6464285: A Solar-type Eclipsing Binary in a Hierarchical Triple System with Quasi-periodic Out-of-eclipse Modulations
Fang-Bin Meng, Li-Ying Zhu, Sheng-Bang Qian +10
We present the first detailed analysis of the solar-type triple system KIC 6464285. Combining long-term, high-precision photometry from Kepler, TESS, and ZTF with low-resolution sp…
Observational Properties of Cephei Stars: 88 new samples discovered Based on TESS and Gaia Data
Xiang-dong Shi, Sheng-bang Qian, Li-ying Zhu +5
We present a systematic investigation of Cephei (BCEP) stars by integrating photometric data from the Transiting Exoplanet Survey Satellite (TESS) with astrometric parameters…
Observational Properties of 155 Cephei pulsating variable stars
Xiang-dong Shi, Sheng-bang Qian, Li-ying Zhu +3
Cephei pulsating variable (BCEP) stars are the most massive pulsating variable stars in the main sequence, exhibiting both p- and g-mode pulsations. In this study, we identifi…
A catalog of new slowly pulsating B-type stars
Xiang-dong Shi, Sheng-bang Qian, Li-ying Zhu +1
This paper reports the discovery of new slowly pulsating B-type stars. Based on the photometric, spectral, and astrometric data of TESS, LAMOST, and Gaia surveys, we have found 286…
Decoding the Future of Exoplanets: Asteroseismic Confirmation of Subgiant and Red Giant Hosts
Wen-Xu Lin, Sheng-Bang Qian, Li-Ying Zhu +5
Asteroseismology has emerged as a powerful tool to unravel the intricate relationships between evolved stars and their planetary systems. In this study, we leverage this technique…
CZ Aqr: an oscillating eclipsing Algol-type system composed of a Sct primary star and a subgiant star in a quadruple system
Qi-Huan Zeng, Wen-Ping Liao, Sheng-Bang Qian +3
Eclipsing Algol-type systems containing a Scuti (hereafter Sct) star enable precise determination of physical parameters and the investigation of stellar internal structu…
