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
Matekov Azizbek, Azizbek Matekov, Zhu Liying +25
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…
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…
