Radiation-Regulated Spherical Accretion with an Inner Accretion Disk
Cheng-Liang Jiao, Liying Zhu, Xiang-dong Shi +1
We develop a theoretical model for radiation-regulated spherical accretion with an inner accretion disk. In our model, the outer accretion flow remains quasi-spherical and opticall…
A unified framework for hot accretion flows with finite angular momentum: from Bondi-like to disc-like regimes
Cheng-Liang Jiao, Liying Zhu, Er-gang Zhao +1
Observations of X-ray luminous elliptical galaxies suggest that the accretion rate onto the central supermassive black hole can reach a substantial fraction of the Bondi rate. Howe…
HD 26172: an active solar-type subgiant in a close binary system
Fang-Bin Meng, Li-Ying Zhu, Sheng-Bang Qian +5
We present the first comprehensive photometric and spectroscopic analysis of the RS CVn system HD 26172, robustly determining the previously debated evolutionary state of its prima…
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…
