SN 2020wnt: a slow-evolving carbon-rich superluminous supernova with no O <scp>ii</scp> lines and a bumpy light curve
ABSTRACT We present the analysis of SN 2020wnt, an unusual hydrogen-poor superluminous supernova (SLSN-I), at a redshift of 0.032. The light curves of SN 2020wnt are characterized by an early bump lasting ∼5 d, followed by a bright main peak. The SN reaches a peak absolute magnitude of M$_{r}^{\rm max}=-20.52\pm …
