Serendipitous detection of the dusty Type IIL SN 1980K with JWST/MIRI

Szanna Zsíros, Tamás Szalai, Ilse De Looze +39

We present mid-infrared (mid-IR) imaging of the Type IIL supernova (SN) 1980K with the James Webb Space Telescope (JWST) more than 40 yr post-explosion. SN 1980K, located in the ne…

A Luminous Red Supergiant and Dusty Long-period Variable Progenitor for SN 2023ixf

Jacob E. Jencson, Jeniveve Pearson, Emma R. Beasor +23

We analyze pre-explosion near- and mid-infrared (IR) imaging of the site of SN 2023ixf in the nearby spiral galaxy M101 and characterize the candidate progenitor star. The star dis…

A Comprehensive Investigation of Gamma-Ray Burst Afterglows Detected by TESS

Hugh Roxburgh, Ryan Ridden-Harper, Zachary G. Lane +9

Gamma-ray bursts produce afterglows that can be observed across the electromagnetic spectrum and can provide insight into the nature of their progenitors. While most telescopes tha…

A Low-Mass Helium Star Progenitor Model for the Type Ibn SN 2020nxt

Qinan Wang, Anika Goel, Luc Dessart +55

A growing number of supernovae (SNe) are now known to exhibit evidence for significant interaction with a dense, pre-existing, circumstellar medium (CSM). SNe Ibn comprise one such…

SN 2021zny: an early flux excess combined with late-time oxygen emission suggests a double white dwarf merger event

Georgios Dimitriadis, Kate Maguire, Viraj R. Karambelkar +28

We present a photometric and spectroscopic analysis of the ultra-luminous and slowly evolving 03fg-like Type Ia SN 2021zny. Our observational campaign starts from hours a…

JWST Discovery of Dust Reservoirs in Nearby Type IIP Supernovae 2004et and 2017eaw

Melissa Shahbandeh, Arkaprabha Sarangi, Tea Temim +36

Supernova (SN) explosions have been sought for decades as a possible source of dust in the Universe, providing the seeds of galaxies, stars, and planetary systems. SN 1987A offers…
