Circumstellar interaction signatures in the low luminosity type II SN 2021gmj

Nicolas Meza-Retamal, Yize Dong, K. Azalee Bostroem +25

We present comprehensive optical observations of SN~2021gmj, a Type II supernova (SN~II) discovered within a day of explosion by the Distance Less Than 40~Mpc (DLT40) survey. Follo…

The Early Ultraviolet Light-Curves of Type II Supernovae and the Radii of Their Progenitor Stars

Ido Irani, Jonathan Morag, Avishay Gal-Yam +18

We present a sample of 34 normal SNe II detected with the Zwicky Transient Facility, with multi-band UV light-curves starting at days after explosion, as well as X-ray d…

Evidence of weak circumstellar medium interaction in the Type II SN 2023axu

Manisha Shrestha, Jeniveve Pearson, Samuel Wyatt +34

We present high-cadence photometric and spectroscopic observations of SN~2023axu, a classical Type II supernova with an absolute -band peak magnitude of mag. SN~…

Implications for the Explosion Mechanism of Type Ia Supernovae from their Late-time Spectra

Jialian Liu, Xiaofeng Wang, Alexei V. Filippenko +10

Late-time spectra of Type Ia supernovae (SNe Ia) are important in clarifying the physics of their explosions, as they provide key clues to the inner structure of the exploding whit…

1100 days in the life of the supernova 2018ibb -- The best pair-instability supernova candidate, to date

Steve Schulze, Claes Fransson, Alexandra Kozyreva +63

Abridged - Stars with ZAMS masses between 140 and are thought to explode as pair-instability supernovae (PISNe). During their thermonuclear runaway, PISNe can produce…

SN 2020udy: a SN Iax with strict limits on interaction consistent with a helium-star companion

Kate Maguire, Mark R. Magee, Giorgos Leloudas +24

Early observations of transient explosions can provide vital clues to their progenitor origins. In this paper we present the nearby Type Iax (02cx-like) supernova (SN), SN 2020udy…
