Two Decades of Dust Evolution in SN 2005af through JWST, Spitzer, and Chemical Modeling
Arkaprabha Sarangi, Szanna Zsiros, Tamas Szalai +20
The evolution of dust in core-collapse supernovae (SNe), in general, is poorly constrained owing to a lack of infrared observations after a few years from explosion. Most theories…
JWST/MIRI detects the dusty SN1993J about 30 years after explosion
Tamás Szalai, Szanna Zsíros, Jacob Jencson +37
Core-collapse supernovae (CCSNe) have long been considered to contribute significantly to the cosmic dust budget. New dust cools quickly and is therefore detectable at mid-infrared…
