Abstract

Despite the importance of Type Ia supernovae as standard candles for cosmology and to the chemical evolution of the Universe, it is still not completely understood how these explosions take place and which are the progenitor systems. In this contribution we present a Monte Carlo code for modelling the time-dependent 3D radiative transfer problem in chemically inhomogeneous models of supernova ejecta. We avoid free parameters so that a direct comparison between synthetic spectra and light curves calculated from hydrodynamic explosion models and observations becomes feasible. Calculations for the well known W7 explosion model and first applications to multidimensional toy models are shown.
