Mesoscale Turbulence in Type Ia Supernova Deflagrations: Buoyancy-Driven Fuel Heating and Prospects for Delayed-Detonations
Ezra Brooker, Andrey Zhiglo, Tomasz Plewa
The aim of this work is to characterize the thermodynamic state of fuel mixed into the turbulent flame brush in the context of the Zel'dovich deflagration-to-detonation transition…
Detonating Failed Deflagration Model of Thermonuclear Supernovae I. Explosion Dynamics
Tomasz Plewa
We present a detonating failed deflagration model of Type Ia supernovae. In this model, the thermonuclear explosion of a massive white dwarf follows an off-center deflagration. We…
Crushing of interstellar gas clouds in supernova remnants. I. The role of thermal conduction and radiative losses
S. Orlando, G. Peres, F. Reale +4
We model the hydrodynamic interaction of a shock wave of an evolved supernova remnant with a small interstellar gas cloud like the ones observed in the Cygnus loop and in the Vela…
Type Ia Supernovae: Simulations and Nucleosynthesis
E. F. Brown, A. C. Calder, T. Plewa +3
We present our first nucleosynthesis results from a numerical simulation of the thermonuclear disruption of a static cold Chandrasekhar-mass C/O white dwarf. The two-dimensional si…
Type Ia Supernova Explosion: Gravitationally Confined Detonation
Tomasz Plewa, Alan Calder, Don Lamb
We present a new mechanism for Type Ia supernova explosions in massive white dwarfs. The proposed scenario follows from relaxing the assumption of symmetry in the model and involve…
Mapping Initial Hydrostatic Models in Godunov Codes
M. Zingale, L. J. Dursi, J. ZuHone +12
We look in detail at the process of mapping an astrophysical initial model from a stellar evolution code onto the computational grid of an explicit, Godunov type code while maintai…
