Ascertaining the Core Collapse Supernova Mechanism: An Emerging Picture?
A. Mezzacappa, S. W. Bruenn, J. M. Blondin +2
Here we present the results from two sets of simulations, in two and three spatial dimensions. In two dimensions, the simulations include multifrequency flux-limited diffusion neut…
Modeling core collapse supernovae in 2 and 3 dimensions with spectral neutrino transport
S. W. Bruenn, C. J. Dirk, A. Mezzacappa +4
The overwhelming evidence that the core collapse supernova mechanism is inherently multidimensional, the complexity of the physical processes involved, and the increasing evidence…
Capturing the Fire: Flame Energetics and Neutronizaton for Type Ia Supernova Simulations
A. C. Calder, D. M. Townsley, I. R. Seitenzahl +6
We develop and calibrate a realistic model flame for hydrodynamical simulations of deflagrations in white dwarf (Type Ia) supernovae. Our flame model builds on the advection-diffus…
On the Evolution of Thermonuclear Flames on Large Scales
Ju Zhang, O. E. Bronson Messer, Alexei M. Khokhlov +1
The thermonuclear explosion of a massive white dwarf in a Type Ia supernova explosion is characterized by vastly disparate spatial and temporal scales. The extreme dynamic range in…
The consequences of nuclear electron capture in core collapse supernovae
W. R. Hix, O. E. B. Messer, A. Mezzacappa +5
The most important weak nuclear interaction to the dynamics of stellar core collapse is electron capture, primarily on nuclei with masses larger than 60. In prior simulations of co…
Supernova Science at Spallation Neutron Sources
W. R. Hix, A. Mezzacappa, O. E. B. Messer +1
New facilities to measure neutrino-nucleus cross sections, such as those possible in conjunction with spallation neutron sources, could provide an experimental foundation for the m…
The Neutrino Signal in Stellar Core Collapse and Postbounce Evolution
M. Liebendoerfer, A. Mezzacappa, O. E. B. Messer +3
General relativistic multi-group and multi-flavor Boltzmann neutrino transport in spherical symmetry adds a new level of detail to the numerical bridge between microscopic nuclear…
A Finite Difference Representation of Neutrino Radiation Hydrodynamics in Spherically Symmetric General Relativistic Space-Time
M. Liebendoerfer, O. E. B. Messer, A. Mezzacappa +3
We present an implicit finite difference representation for general relativistic radiation hydrodynamics in spherical symmetry. Our code, Agile-Boltztran, solves the Boltzmann tran…
The importance of neutrino opacities for the accretion luminosity in spherically symmetric supernova models
M. Liebendoerfer, O. E. B. Messer, A. Mezzacappa +3
Based on general relativistic three-flavor Boltzmann neutrino transport, we compare simulations of the postbounce evolution for five different stellar progenitors with 13 and 20 so…
General Relativistic Simulations of Stellar Core Collapse and Postbounce Evolution with Boltzmann Neutrino Transport
Matthias Liebendoerfer, O. E. Bronson Messer, Anthony Mezzacappa +1
We present self-consistent general relativistic simulations of stellar core collapse, bounce, and postbounce evolution for 13, 15, and 20 solar mass progenitors in spherical symmet…
Probing the gravitational well: No supernova explosion in spherical symmetry with general relativistic Boltzmann neutrino transport
Matthias Liebendoerfer, Anthony Mezzacappa, Friederich-Karl Thielemann +3
We report on the stellar core collapse, bounce, and postbounce evolution of a 13 solar mass star in a self-consistent general relativistic spherically symmetric simulation based on…
Simulation of the Spherically Symmetric Stellar Core Collapse, Bounce, and Postbounce Evolution of a 13 Solar Mass Star with Boltzmann Neutrino Transport, and Its Implications for the Supernova Mechanism
Anthony Mezzacappa, Matthias Liebendoerfer, O. E. Bronson Messer +3
With exact three-flavor Boltzmann neutrino transport, we simulate the stellar core collapse, bounce, and postbounce evolution of a 13 solar mass star in spherical symmetry, the New…
A Comparison of Boltzmann and Multigroup Flux-Limited Diffusion Neutrino Transport During the Postbounce Shock Reheating Phase in Core Collapse Supernovae
Bronson Messer, Anthony Mezzacappa, Steve Bruenn +1
We compare Newtonian three-flavor multigroup Boltzmann (MGBT) and (Bruenn's) multigroup flux-limited diffusion (MGFLD) neutrino transport in postbounce core collapse supernova envi…
Neutrino-driven supernovae: Boltzmann neutrino transport and the explosion mechanism
O. E. B. Messer, A. Mezzacappa, S. W. Bruenn +1
Core-collapse supernovae are, despite their spectacular visual display, neutrino events. Virtually all of the 10^53 ergs of gravitational binding energy released in the formation o…
