W UMa-Type Contact Binaries in the Tidal Tails of Young Open Cluster COIN-Gaia 25 and Mamajek 4
Xiang Bin, Liu Liang, Zhu Liying +2
Star clusters, as dynamically rich environments, are thought to be important sites for the formation of contact binaries. To investigate this, we conducted a systematic search for…
WFST Supernovae in the First Year: III. Systematical Study of the Photometric Behavior of Early-phase Core-collapse Supernovae
Junhan Zhao, Ji-an Jiang, Zelin Xu +22
We investigate the multiband photometric properties of seven supernovae (SNe) showing double-peaked light-curve evolution and prominent shock-cooling emission, observed by the Wide…
An Archival Optical Counterpart Search for Extragalactic Fast X-Ray Transients Discovered by Einstein Probe
Run-Duo Liang, Wen-Xiong Li, Liang-Duan Liu +50
Extragalactic fast X-ray transients (eFXTs) represent a rapidly growing class of high-energy phenomena, whose physical origins remain poorly understood. With its wide-field, sensit…
SN 2024igg: A Super-Chandrasekhar/03fg-like SN exhibiting C II-dominated spectra after explosion
Jialian Liu, Xiaofeng Wang, Liyang Chen +14
We present and analyze photometric and spectroscopic observations of the Type Ia supernova (SN Ia) 2024igg, another ``super-Chandrasekhar'' (or 03fg-like) SN whose strong C II $\la…
KIC 7914906: An Eclipsing Heartbeat Star with Tidally Excited Oscillations and Gamma Doradus/Delta Scuti Hybrid Pulsations
Min-Yu Li, Sheng-Bang Qian, Li-Ying Zhu +6
We present the eclipsing Heartbeat Star KIC 9704906 with tidally excited oscillations (TEOs) and gamma Doradus/delta Scuti hybrid pulsations. The derived parameters show that it ha…
