Approximating General Relativity in Core-Collapse Supernova Simulations
Steven A. Fromm, Vassilios Mewes, O. E. Bronson Messer +3
We present formulations of effective potentials suitable for approximating general relativistic effects in Newtonian simulations of core-collapse supernovae. Assuming a spherically…
The Impact of Resolution on Double-Detonation Models for Type Ia Supernovae
Fernando Rivas, J. Austin Harris, W. Raphael Hix +1
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, s…
Three Dimensional Core-Collapse Supernova Simulations with 160 Isotopic Species Evolved to Shock Breakout
Michael A. Sandoval, W. Raphael Hix, O. E. Bronson Messer +2
We present three-dimensional simulations of core-collapse supernovae using the FLASH code that follow the progression of the explosion to the stellar surface, starting from neutrin…
A DG-IMEX method for two-moment neutrino transport: Nonlinear solvers for neutrino-matter coupling
M. Paul Laiu, Eirik Endeve, Ran Chu +2
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 neut…
Gravitational-wave signal of a core-collapse supernova explosion of a 15 Solar mass star
Anthony Mezzacappa, Pedro Marronetti, Ryan E. Landfield +8
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…
Catching Element Formation In The Act
Chris L. Fryer, Frank Timmes, Aimee L. Hungerford +216
Gamma-ray astronomy explores the most energetic photons in nature to address some of the most pressing puzzles in contemporary astrophysics. It encompasses a wide range of objects…
Gravitational wave signals from multi-dimensional core-collapse supernova explosion simulations
K. N. Yakunin, E. Endeve, A. Mezzacappa +9
In this work we report briefly on the gravitational wave (GW) signal computed in the context of a self-consistent, 3D simulation of a core-collapse supernova (CCSN) explosion of a…
The Gravitational Wave Signal of a Core Collapse Supernova Explosion of a 15M Star
Konstantin N. Yakunin, Anthony Mezzacappa, Pedro Marronetti +7
In this Letter, we report on the gravitational wave signal computed in the context of an , three-dimensional simulation of a core collapse supernova explosion, beginni…
The Multi-Dimensional Character of Core-Collapse Supernovae
W. R. Hix, E. J. Lentz, S. W. Bruenn +7
Core-collapse supernovae, the culmination of massive stellar evolution, are spectacular astronomical events and the principle actors in the story of our elemental origins. Our unde…
Multimessengers from 3D Core-Collapse Supernovae
Konstantin N. Yakunin, Pedro Marronetti, Anthony Mezzacappa +5
We present gravitational wave and neutrino signatures obtained in our first principle 3D core-collapse supernova simulation of 15M non-rotating progenitor with Chimera code. Observ…
Gravitational Wave Signatures of Ab Initio Two-Dimensional Core Collapse Supernova Explosion Models for 12-25 Solar Masses Stars
Konstantin N. Yakunin, Anthony Mezzacappa, Pedro Marronetti +9
We present the gravitational waveforms computed in ab initio two-dimensional core collapse supernova models evolved with the Chimera code for progenitor masses between 12 and 25 so…
