Following multi-dimensional Type Ia supernova explosion models to homologous expansion
arXiv:astro-ph/0408296 · doi:10.1051/0004-6361:20041700
Abstract
The last years have witnessed a rapid development of three-dimensional models of Type Ia supernova explosions. Consequently, the next step is to evaluate these models under variation of the initial parameters and to compare them with observations. To calculate synthetic lightcurves and spectra from numerical models, it is mandatory to follow the evolution up to homologous expansion. We report on methods to achieve this in our current implementation of multi-dimensional Type Ia supernova explosion models. The novel scheme is thoroughly tested in two dimensions and a simple example of a three-dimensional simulation is presented. We discuss to what degree the assumption of homologous expansion is justified in these models.
