Simulation to a Newborn Supernova Remnant from a Low-mass Iron Core Star
Sudarshan Neopane, Michael A. Sandoval, W. Raphael Hix +3
Supernova remnant observations show a high degree of asymmetry, mixing, and inhomogeneity. These asymmetries are seeded during the early seconds of the explosion and are further en…
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…
Comparison of the Core-Collapse Evolution of Two Nearly Equal Mass Progenitors
Stephen W. Bruenn, Andre Sieverding, Eric J. Lentz +6
We compare the core-collapse evolution of a pair of 15.8 stars with significantly different internal structures, a consequence of bimodal variability exhibited by massive…
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…
Implications for Post-Processing Nucleosynthesis of Core-Collapse Supernova Models with Lagrangian Particles
J. Austin Harris, W. Raphael Hix, Merek A. Chertkow +3
We investigate core-collapse supernova (CCSN) nucleosynthesis with self-consistent, axisymmetric (2D) simulations performed using the radiation-hydrodynamics code Chimera. Computat…
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…
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…
Two- and three-dimensional simulations of core-collapse supernovae with CHIMERA
Eric J. Lentz, Stephen W. Bruenn, J. Austin Harris +8
Ascertaining the core-collapse supernova mechanism is a complex, and yet unsolved, problem dependent on the interaction of general relativity, hydrodynamics, neutrino transport, ne…
