Type Ia supernova diversity in three-dimensional models
The use of type Ia supernovae as distance indicators for cosmology has initiated a search for theoretical arguments supporting the empirical calibration methods applied. To this end, as a first step, a sound understanding of the origin of the observed diversity in type Ia supernova properties is needed. Here we present a first systematic study of effects resulting from changing some physical pa...
متن کاملType Ia Supernova Diversity from 3-dimensional Models
We present results from a systematic study of the effects of initial parameters on three-dimensional thermonuclear supernova models. One major challenge to numerical models of thermonuclear supernova explosions is to reproduce the diversity observed among Type Ia supernovae (SNe Ia). With the rapid advancement of three-dimensional models over the past years, systematic studies have become possi...
متن کاملType Ia Supernova Explosion Models: Homogeneity versus Diversity
Type Ia supernovae (SN Ia) are generally believed to be the result of the thermonuclear disruption of Chandrasekhar-mass carbon-oxygen white dwarfs, mainly because such thermonuclear explosions can account for the right amount of Ni, which is needed to explain the light curves and the late-time spectra, and the abundances of intermediate-mass nuclei which dominate the spectra near maximum light...
متن کاملThree-dimensional Modeling of Type Ia Supernova Explosions
Modeling type Ia supernova (SN Ia) explosions in three dimensions allows to eliminate any undetermined parameters and provides predictive power to simulations. This is necessary to improve the understanding of the explosion mechanism and to settle the question of the applicability of SNe Ia in cosmological distance measurements. Since the models contain no tunable parameters, it is also possibl...
متن کاملThree-Dimensional Delayed-Detonation Model of Type Ia Supernova
We study a Type Ia supernova explosion using large-scale three-dimensional numerical simulations based on reactive fluid dynamics with a simplified mechanism for nuclear reactions and energy release. The initial deflagration stage of the explosion involves a subsonic turbulent thermonuclear flame propagating in the gravitational field of an expanding white dwarf. The deflagration produces an in...
