| Abstract: |
Type Ia supernovae (SNe Ia) are a prime tool in observational
cosmology. A relation between their peak luminosities and the shapes of
their light curves allows to infer their intrinsic luminosities and to
use them as distance indicators. This relation has been established
empirically. However, a theoretical understanding is necessary in
order to get a handle on the systematics in SN Ia cosmology. Here, a
model reproducing the observed diversity of normal SNe Ia is
presented. The challenge in the numerical implementation arises from
the vast range of scales involved in the physical
mechanism. Simulating the supernova on scales of the exploding white
dwarf requires specific models of the microphysics involved in the
thermonuclear combustion process. Such techniques are discussed and
results of simulations are presented. |
