The Density Probability Distribution in Compressible Isothermal Turbulence: Solenoidal versus Compressive Forcing
Christoph Federrath, Ralf S. Klessen, Wolfram Schmidt
The probability density function (PDF) of the gas density in turbulent supersonic flows is investigated with high-resolution numerical simulations. In a systematic study, we compar…
A localised subgrid scale model for fluid dynamical simulations in astrophysics II: Application to type Ia supernovae
W. Schmidt, J. C. Niemeyer, W. Hillebrandt +1
The dynamics of the explosive burning process is highly sensitive to the flame speed model in numerical simulations of type Ia supernovae. Based upon the hypothesis that the effect…
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…
Thermonuclear supernova simulations with stochastic ignition
W. Schmidt, J. C. Niemeyer
We apply an ad hoc model for dynamical ignition in three-dimensional numerical simulations of thermonuclear supernovae assuming pure deflagrations. The model makes use of the stati…
Simulations of Turbulent Thermonuclear Burning in Type Ia Supernovae
W. Hillebrandt, M. Reinecke, W. Schmidt +3
Type Ia supernovae have recently received considerable attention because it appears that they can be used as "standard candles" to measure cosmic distances out to billions of light…
