We compare the core-collapse evolution of a pair of 15.8 $M_\odot$ stars with significantly different internal structures, a consequence of bimodal variability exhibited by massive stars during their late evolutionary stages. The 15.78 and 15.79 $M_\

The Impact of Resolution on Double-Detonation Models for Type Ia Supernovae

Autor: Rivas, Fernando, Harris, J. Austin, Hix, W. Raphael, Messer, O. E. Bronson

Thermonuclear supernovae are the result of the violent unbinding of a white dwarf, but the precise nature of the explosion mechanism(s) is a matter of active debate. To this end, several specific scenarios have been proposed to explain the observable

In this white paper, we outline some of the scientific opportunities and challenges related to detection and reconstruction of low-energy (less than 100 MeV) signatures in liquid argon time-projection chamber (LArTPC) detectors. Key takeaways are sum

A DG-IMEX method for two-moment neutrino transport: Nonlinear solvers for neutrino-matter coupling

Autor: Laiu, M. Paul, Endeve, Eirik, Chu, Ran, Harris, J. Austin, Messer, O. E. Bronson

Neutrino-matter interactions play an important role in core-collapse supernova (CCSN) explosions as they contribute to both lepton number and/or four-momentum exchange between neutrinos and matter, and thus act as the agent for neutrino-driven explos

We report on the gravitational wave signal computed in the context of a three-dimensional simulation of a core collapse supernova explosion of a 15 Solar mass star. The simulation was performed with our neutrino hydrodynamics code Chimera. We detail
