A Magnetar Engine and Circumstellar Medium Interaction: Synergistic Effects in Producing Superluminous Supernovae
Guang-Lei Wu, Yun-Wei Yu, Liang-Duan Liu
Superluminous supernovae (SLSNe) are often modeled as being powered either by a central engine or by strong interaction with dense circumstellar material (CSM). These two mechanism…
The Dust Echo Emission of Fast Blue Optical Transients and Application to the Near-Infrared Excess of AT 2018cow
Jing-Yao Li, Yun-Wei Yu, Liang-Duan Liu +1
A near-infrared (NIR) excess has been discovered in the emission of the representative fast blue optical transient (FBOT): AT 2018cow. It was suggested that this NIR excess could b…
EP241021a: A catastrophic collapse/merger of compact star binary leading to the formation of a remnant millisecond magnetar?
Guang-Lei Wu, Yun-Wei Yu, Liang-Duan Liu +7
Observations of fast X-ray transients (FXRTs) with the Einstein Probe have successfully led to the discovery of some unusual extragalactic optical transients. EP241021a is a newly…
Observational properties of 155 O- and B-type massive pulsating stars
Xiang-dong Shi, Sheng-bang Qian, Li-ying Zhu +3
The O- and B-type (OB-type) pulsating stars are important objects to study the structure and evolution of massive stars through asteroseismology. A large amount of data from variou…
