Investigations of Pointwise Ignition of Helium Deflagrations on Neutron Stars
M. Zingale, S. E. Woosley, A. Cumming +7
We look at the spreading of localized temperature perturbations in the accreted fuel layer of a non-rotating neutron star. The pressure at the base of the accreted fuel layer is la…
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…
Onset of Convectionon a Pre-Runaway White Dwarf
L. J. Dursi, A. C. Calder, A. Alexakis +7
Observed novae abundances and explosion energies estimated from observations indicate that there must be significant mixing of the heavier material of the white dwarf (C+O) into th…
Mixing by Non-linear Gravity Wave Breaking on a White Dwarf Surface
A. C. Calder, A. Alexakis, L. J. Dursi +7
We present the results of a simulation of a wind-driven non-linear gravity wave breaking on the surface of a white dwarf. The ``wind'' consists of H/He from an accreted envelope, a…
On Validating an Astrophysical Simulation Code
A. C. Calder, B. Fryxell, T. Plewa +15
We present a case study of validating an astrophysical simulation code. Our study focuses on validating FLASH, a parallel, adaptive-mesh hydrodynamics code for studying the compres…
