Turbulence in a three-dimensional deflagration model for Type Ia supernovae: I. Scaling properties
F. Ciaraldi-Schoolmann, W. Schmidt, J. C. Niemeyer +2
We analyze the statistical properties of the turbulent velocity field in the deflagration model for Type Ia supernovae. In particular, we consider the question of whether turbulenc…
The ignition process in type Ia supernovae: numerical simulations of core temperature perturbations
L. Iapichino, M. Brüggen, W. Hillebrandt +1
The onset of the thermonuclear runaway in a Chandrasekhar-mass white dwarf, leading to the explosion as a type Ia supernova, is studied with hydrodynamical simulations. We investig…
Delayed detonations in full-star models of Type Ia supernova explosions
F. K. Roepke, J. C. Niemeyer
Aims: We present the first full-star three-dimensional explosion simulations of thermonuclear supernovae including parameterized deflagration-to-detonation transitions that occur o…
A localised subgrid scale model for fluid dynamical simulations in astrophysics I: Theory and numerical tests
W. Schmidt, J. C. Niemeyer, W. Hillebrandt
We present a one-equation subgrid scale model that evolves the turbulence energy corresponding to unresolved velocity fluctuations in large eddy simulations. The model is derived i…
Three-dimensional simulations of type Ia supernovae
M. Reinecke, W. Hillebrandt, J. C. Niemeyer
We present the results of three-dimensional hydrodynamical simulations of the subsonic thermonuclear burning phase in type Ia supernovae. The burning front model contains no adjust…
On the Explosion Mechanism of SNe Type Ia
M. Reinecke, J. C. Niemeyer, W. Hillebrandt
In this article we discuss the first simulations of two- and three-dimensional Type Ia supernovae with an improved hydrodynamics code. After describing the various enhancements, th…
