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…
Issues with Core-Collapse Supernova Progenitor Models
Stephen W. Bruenn
The status of core collapse supernoova progenitor models is reviewed with a focus on some of the current uncertainties arising from the difficulties of modeling important macrophys…
Fluid Stability Below the Neutrinospheres of Supernova Progenitors and the Dominant Role of Lepto-Entropy Fingers
S. W. Bruenn, E. A. Raley, A. Mezzacappa
We have developed a formalism for analyzing the stability of a fluid in the presence of neutrinos of all flavors and in the presence of a gravitational field. When applied to an ex…
General Relativistic Effects in the Core Collapse Supernova Mechanism
S. W. Bruenn, K. R. De Nisco, A. Mezzacappa
We apply our recently developed code for spherically symmetric, fully general relativistic (GR) Lagrangian hydrodynamics and multigroup flux-limited diffusion neutrino transport to…
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…
