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 f…
Accretion rates of stellar-mass compact objects embedded in AGN discs
Cheng-Liang Jiao, Liying Zhu, Er-gang Zhao +1
Stellar-mass compact objects (COs) embedded in active galactic nucleus (AGN) discs are commonly assumed to accrete via Bondi or Bondi-Hoyle-Lyttleton (BHL) prescriptions, neglectin…
Orbital and Pulsation Analysis of 42 Heartbeat Stars Discovered in TESS Data
Min-Yu Li, Sheng-Bang Qian, Ai-Ying Zhou +7
Heartbeat stars (HBSs) are ideal laboratories for studying the formation and evolution of binary stars in eccentric orbits and their mutual tidal interactions. We present 42 new HB…
Spherically Symmetric Accretion with Self-Gravity: Analytical Formulae and Numerical Validation
Cheng-Liang Jiao, Er-gang Zhao, Liying Zhu +1
Spherically symmetric accretion incorporating self-gravity constitutes a three-point boundary value problem (TPBVP) governed by constraints at the outer boundary, sonic point, and…
Heartbeat Stars Recognition Based on Recurrent Neural Networks: Method and Validation
Min-Yu Li, Sheng-Bang Qian, Li-Ying Zhu +7
Since the variety of their light curve morphologies, the vast majority of the known heartbeat stars (HBSs) have been discovered by manual inspection. Machine learning, which has al…
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…
