Fast Blue Optical Transients due to Circumstellar Interaction and the Mysterious Supernova SN 2018gep

no code implementations11 Mar 2021 Shing-Chi Leung, Jim Fuller, Ken'ichi Nomoto

The fast rise in luminosity of this SN (spectroscopically classified as a broad-lined Type Ic SN), indicates that the ejecta interacts with a dense circumstellar medium (CSM), while an additional energy source such as $^{56}$Ni-decay is required to explain the late-time light curve.

Chemical abundances in Sgr A East: evidence for a type Iax supernova remnant

no code implementations26 Jun 2020 Ping Zhou, Shing-Chi Leung, Zhiyuan Li, Ken'ichi Nomoto, Jacco Vink, Yang Chen

We report evidence that SNR Sgr A East in the Galactic center resulted from a pure turbulent deflagration of a Chandrasekhar-mass carbon-oxygen WD, an explosion mechanism used for type Iax SNe.
