Double “acct”: A Distinct Double-peaked Supernova Matching Pulsational Pair Instability Models

The Astrophysical Journal Letters
We present multiwavelength data of SN 2020acct, a double-peaked stripped-envelope supernova (SN) in NGC 2981 at ∼150 Mpc. The two peaks are temporally distinct, with maxima separated by 58 rest-frame days and a factor of 20 reduction in flux between. The

Hydrogen-Poor Core-Collapse Supernovae

, 2016
Hydrogen-poor core-collapse supernovae (SNe) signal the explosive death of stars more massive than the progenitors of hydrogen-rich core-collapse supernovae, i.e., approximately in the range 15-50 M☉ in main sequence. Since hydrogen-poor core-collapse supernovae include those that accompany gamma-ray bursts (GRBs), which were all rigorously identified ...

Dramatic Rebrightening of the Type-changing Stripped-envelope Supernova SN 2023aew

The Astrophysical Journal
Multipeaked supernovae with precursors, dramatic light-curve rebrightenings, and spectral transformation are rare, but are being discovered in increasing numbers by modern night-sky transient surveys like the Zwicky Transient Facility.

An Extended Closure Relation by LightGBM for Neutrino Radiation Transport in Core-collapse Supernovae

The Astrophysical Journal
We developed a machine learning model using LightGBM, one of the most popular gradient-boosting decision tree methods these days, to predict the Eddington tensor, or the second-order angular moment, for neutrino radiation transport in core-collapse ...
