Two Potential Exoplanets around A-type Stars Selected from 18 Planetary Candidates
Yi-fan Luo, Wen-Ping Liao, Sheng-Bang Qian +2
We screen and analyze exoplanet candidates around A-type stars (defined as Teff between 7500 and 10,000 K) observed by the Transiting Exoplanet Survey Satellite to evaluate their l…
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…
Comprehensive Parameter Determination of Exoplanet through Asteroseismic Host Star Constraints
Wen-Xu Lin, Sheng-Bang Qian, Li-Ying Zhu +5
This study develops a robust framework for exoplanet characterization by leveraging asteroseismic constraints on host stars. Using precise photometric data from missions such as \t…
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…
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…
Evolutionary states and triplicity of four massive semi-detached binaries with long-term decreasing orbital periods in the LMC
Fu-Xing Li, Sheng-Bang Qian, Li-ying Zhu +6
The massive semi-detached binary with a long-term decreasing orbital period may involve a rapid mass-transfer phase in Case A, and thus they are good astrophysical laboratories for…
