The Eye of Sauron in SN 2025ngs: a Short-plateau Cousin of SN 1998S with Evidence for a Ring-like Circumstellar Medium
Conor L. Ransome, David J. Sand, K. Azalee Bostroem +35
Interacting supernovae probe the twilight years of massive stars, exhibiting signatures of interaction between the supernova ejecta and surrounding material expelled from the proge…
SN2023ixf in Messier 101: the twilight years of the progenitor as seen by Pan-STARRS
Conor L. Ransome, V. Ashley Villar, Anna Tartaglia +28
The nearby type II supernova, SN2023ixf in M101 exhibits signatures of early-time interaction with circumstellar material in the first week post-explosion. This material may be the…
SN2023ixf in Messier 101: A Variable Red Supergiant as the Progenitor Candidate to a Type II Supernova
Charles D. Kilpatrick, Ryan J. Foley, Wynn V. Jacobson-Galán +15
We present pre-explosion optical and infrared (IR) imaging at the site of the type II supernova (SN II) 2023ixf in Messier 101 at 6.9 Mpc. We astrometrically registered a ground-ba…
A systematic reclassification of type IIn supernovae
C. L. Ransome, S. M. Habergham-Mawson, M. J. Darnley +3
Type IIn supernovae (SNe IIn) are a relatively infrequently observed subclass of SNe whose photometric and spectroscopic properties are varied. A common thread among SNe IIn are th…
