Rapid Variability and Broadband Spectral Modeling in the Flaring Activity of BL Lacertae

Xin Chang, Dingrong Xiong, Chenxu Liu +17

We report a multi-wavelength study of two flaring episodes of the blazar BL Lacertae during MJD 60500-60800 (9 July 2024 - 5 May 2025). The source reached a daily-averaged -ray…

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…

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…

Tidally Trapped Two-pole Pulsations Discovered in a Close Binary with a Massive Cephei Star

Ping Li, Wen-Ping Liao, Sheng-Bang Qian +4

Tidally tilted pulsators (TTPs), whose pulsation axis aligns with the binary's semi-major axis, represent a newly established class of oscillators in binary systems. While all prev…

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…

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…

KM UMa: An active short-period detached eclipsing binary in a hierarchical quadruple system

Fangbin Meng, Liying Zhu, Nianping Liu +4

The first detailed photometric and spectroscopic analysis of the G-type eclipsing binary KM UMa is presented, which indicates that the system is a short-period detached eclipsing b…

Deep and low mass-ratio contact binaries and their third bodies

Liying Zhu, Shengbang Qian, Wenping Liao +6

Deep and low mass-ratio contact binaries (DLMCBs) are believed to be in the final stage of their contact phase, potentially leading to the formation of fast-rotating single stars s…

CSS_J154915.7+375506: A low-mass-ratio marginal contact binary system with a hierarchical third body

Jin-Feng Wu, Li-Ying Zhu, Azizbek Matekov +6

We presented the multi-filter light curves of CSS_J154915.7+375506 inaugurally, which were observed by the 1.5 m AZT-22 telescope at Maidanak Astronomical Observatory. A low-resolu…
