Properties of the circumstellar matter around the pair-instability supernova candidate SN 2018ibb revealed by its light curve
Takashi J. Moriya, Steve Schulze, Alexander Heger +2
SN 2018ibb is one of the best pair-instability supernova (PISN) candidates identified to date. It, however, showed unexpected blue flux excess in late-phase spectra, likely origina…

Electron-capture Supernova Candidates from Light Curves: Implications for Their Progenitors and Explosion Properties
Masato Sato, Nozomu Tominaga, Sergei I. Blinnikov +5
Core-collapse supernovae are explosions of massive stars. While most massive stars end as iron-core-collapse supernovae, less massive stars are expected to explode as electron-capt…
