Exploring the effect of mixing in Low-Luminosity Type IIp Supernovae by modeling SN 2024abfl
Akshith Karri, Abigail Polin, Paul Duffell
Low-luminosity Type IIp supernovae (LLSNe) are SN IIps with peak magnitudes > -15.5 and plateau magnitudes between -13.5 and -15.5 in the V band. SN 2024abfl is an LLSN with a uniq…

A Novel Parameterization for Rapid Cooling in Supernova Remnants, with applications to the Pa 30 nebula
Miranda Pikus, Paul Duffell, Soham Mandal +1
We systematically study how cooling creates structural changes in supernova remnants as they evolve. Inspired by the peculiar morphology of the Pa 30 nebula, we adopt a framework i…
