The innermost zones of core collapse supernovae

, 2005
We achieve successful explosions (of otherwise non-explosive models) by enhancing the neutrino luminosity in two different ways. The resulting electron fraction Y_e in the innermost ejecta reaches or in some zones even exceeds 0.5.

Multi-energy diffuse neutrino fluxes originating from core-collapse supernovae [PDF]

A comprehensive framework is proposed for the diffuse neutrino fluxes attributed to two different physical processes in core collapse of massive stars. In this scheme, models of thermal MeV-scale neutrinos produced at the core of collapsing stars and non-

Coupled Shock Cooling and Radioactive Heating in SN 2024aecx: An Extended Envelope and Rapid Optical Decline

The Astrophysical Journal
SN 2024aecx is a nearby, rapidly evolving stripped-envelope supernova with a prominent double-peaked ultraviolet–optical light curve. We model its multiband evolution with an extended version of TransFit , in which the early shock-cooling emission and ...

SN 2023gfo: A Peculiar Type IIP Supernova with High Luminosity and Normal Plateau Duration

The Astrophysical Journal
We present near-infrared (NIR) and optical observations of the highly reddened Type IIP supernova (SN) 2023gfo in the nearby galaxy NGC 4995 ( d  = 26.4 ± 3.2 Mpc), which reached a high peak luminosity of M _V  = −18.6 mag.

SN 2024abvb: A Type Icn Supernova in the Outskirts of Its Host Galaxy

The Astrophysical Journal
We present multiband photometric and spectroscopic observations of supernova (SN) 2024abvb, which exhibits early-time prominent photoionized narrow emission lines of C II superposed on a blue continuum.

SN 2021ukt: A Transitional Supernova with a Short Plateau and Persistent Interaction

The Astrophysical Journal
We present spectroscopic and photometric observations of SN 2021ukt, a peculiar short-plateau object that was originally identified as a Type IIn supernovae (SN) and later underwent an unprecedented transition to a Type Ib (possibly Type IIb) SN.
