Impacts of Multidimensional Progenitor Perturbations on Core-Collapse Supernova Explosions
Chien-Hui Chen, Eric J. Lentz, W. Raphael Hix +3
Numerical studies of core-collapse supernovae have demonstrated the importance of non-radial motions in pre-collapse progenitors on the explosion outcome. We use the CHIMERA neutri…
Tracer particles for core-collapse supernova nucleosynthesis: The advantages of moving backward
Andre Sieverding, Preston G. Waldrop, J. Austin Harris +4
After decades, the theoretical study of core-collapse supernova explosions is moving from parameterized, spherically symmetric models to increasingly realistic multi-dimensional si…
Core Collapse Supernova Gravitational Wave Emission for Progenitors of 9.6, 15, and 25 Solar Masses
Anthony Mezzacappa, Pedro Marronetti, Ryan E. Landfield +8
We present gravitational wave emission predictions based on three core collapse supernova simulations corresponding to three different progenitor masses. The masses span a large ra…
On the character of turbulence in self-consistent models of core-collapse supernovae
Jordi Casanova, Eirik Endeve, Eric J. Lentz +4
Neutrino-driven convection plays a crucial role in the development of core-collapse supernova (CCSN) explosions. However, the complex mechanism that triggers the shock revival and…
A Neutrino-Driven Core Collapse Supernova Explosion of a 15 M Star
Anthony Mezzacappa, Eric J. Lentz, Stephen W. Bruenn +8
We present results from an ab initio three-dimensional, multi-physics core collapse supernova simulation for the case of a 15 M progenitor. Our simulation includes multi-frequency…
Three-dimensional core-collapse supernova simulated using a 15 progenitor
Eric J. Lentz, Stephen W. Bruenn, W. Raphael Hix +7
We have performed ab initio neutrino radiation hydrodynamics simulations in three and two spatial dimensions (3D and 2D) of core-collapse supernovae from the same 15 prog…
Recent Progress on Ascertaining the Core Collapse Supernova Explosion Mechanism
Anthony Mezzacappa, Stephen W. Bruenn, Eric J. Lentz +8
We have been working within the fundamental paradigm that core collapse supernovae (CCSNe) may be neutrino driven, since the first suggestion of this by Colgate and White nearly fi…
Advancing Nucleosynthesis in Self-consistent, Multidimensional Models of Core-Collapse Supernovae
J. Austin Harris, W. Raphael Hix, Merek A. Chertkow +7
We investigate core-collapse supernova (CCSN) nucleosynthesis in polar axisymmetric simulations using the multidimensional radiation hydrodynamics code CHIMERA. Computational costs…
The Development of Explosions in Axisymmetric Ab Initio Core-Collapse Supernova Simulations of 12-25 Stars
Stephen W. Bruenn, Eric J. Lentz, W. Raphael Hix +9
We present four ab initio axisymmetric core-collapse supernova simulations for 12, 15, 20, and 25 progenitors. All of the simulations yield explosions and have been evolv…
Two- and Three-Dimensional Multi-Physics Simulations of Core Collapse Supernovae: A Brief Status Report and Summary of Results from the "Oak Ridge" Group
Anthony Mezzacappa, Stephen W. Bruenn, Eric J. Lentz +8
We summarize the results of core collapse supernova theory from one-, two-, and three-dimensional models and provide a snapshot of the field at this time. We also present results f…
