    High-cadence ultraviolet, optical, and near-infrared photometric and low-resolution spectroscopic observations of the peculiar Type II supernova (SN) 2018hna are presented. The early-phase multiband light curves (LCs) ...
  • The Unluckiest Star: A Spectroscopically Confirmed Repeated Partial Tidal Disruption Event AT 2022dbl 
    Lin, Zheyu; Jiang, Ning; Wang, Tinggui; Kong, Xu; Li, Dongyue; He, Han; Wang, Yibo; Zhu, Jiazheng; Li, Wentao; Jiang, Ji-an; Singh, Avinash; Teja, Rishabh Singh; Sahu, D. K; Jin, Chichuan; Maeda, Keiichi; Huang, Shifeng (American Astronomical Society, 2024-08-10)
    The unluckiest star orbits a supermassive black hole elliptically. Every time it reaches the pericenter, it shallowly enters the tidal radius and gets partially tidally disrupted, producing a series of flares. Confirmation ...
