Frequent Optical Flares in an M-type Detached Eclipsing Binary TIC 349005337
Xiao Zhou, Liying Zhu, Wei Hu +4
A comprehensive photometric and spectroscopic analysis of TIC 349005337, a highly active M-type detached eclipsing binary with an orbital period of 2.6079133 days, is presented uti…
The Survival Paradox of Close-In Planets Orbiting Red Clump Giants
Wen-Xu Lin, Sheng-Bang Qian, Qi-Bin Sun +9
Close-in planets orbiting core-helium-burning red-clump (RC) giants directly challenge tidal-engulfment theory, which predicts that planets within about 1 au of Sun-like stars shou…
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…
Eclipse Properties and Superhump Evolution in the SU UMa-Type Dwarf Nova Z Cha
Qi-Bin Sun, Sheng-Bang Qian, Li-Ying Zhu +10
The advent of large-scale time-domain surveys provides both opportunities and challenges for understanding accretion disk evolution in cataclysmic variables (CVs). Using high-caden…
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…
Universal scaling between magnetar field and initial spin period for short gamma ray bursts
Qin-Mei Li, Qi-Bin Sun, Sheng-Bang Qian +5
The -- correlation serves as a critical probe of magnetar engine physics. Although this scaling relation has been firmly established for long gamma-ray bursts (lGRBs), sy…
CW Cas: A solar-type contact binary system with an unseen third companion in a hierarchical quadruple system
Azizbek Matekov, Liying Zhu, Linjia Li +11
We present a comprehensive multiband photometric and spectroscopic study of the G-type binary CW Cas whose parameters have not been well determined. Our double-lined spectroscopic…
Diversity in Evolutionary Status and Magnetic Activity among Solar-Type Twin Detached Eclipsing Binaries
Fang-Bin Meng, Li-Ying Zhu, Sheng-Bang Qian +9
We present a combined photometric and spectroscopic analysis of four detached eclipsing binaries (KIC 8957954, KIC 10593759, KIC 8302455, and TIC 207398432), all of which exhibit c…
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…
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…
Asteroseismology and Dynamics Reveal Interior Structure and Coeval Evolution in the Triply Post-Main-Sequence system DG Leo
Ping Li, Wen-Ping Liao, Sheng-Bang Qian +4
Scuti stars in binary or multiple systems serve as crucial probes for studying stellar pulsation and evolution. However, many such systems are not ideal for asteroseismology du…
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…
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…
A possible explanation of W-type phenomena in V694 Peg
Hu-Shan Xu, Li-Ying Zhu
Three sets of complete multi-color light curves of V694 Peg observed in 2013, 2015 and 2019 were presented and analyzed. Our photometric solutions show that this system is an A-typ…
