Type Ia supernova diversity: Standardizing the candles
Future use of type Ia supernovae for cosmology aims not only to determine the equation of state of dark energy, but also to constrain possible variations in its value. To achieve this goal, supernovae need to become better calibrated standard candles — not only to improve the precision of the measurement, but more importantly to gain better control over systematic uncertainties in order to ensu...
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 کاملType 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 کاملTime-dependence Effects in Photospheric-Phase Type II Supernova Spectra
We have incorporated time-dependent terms into the statistical and radiative equilibrium calculations of the non-LTE line-blanketed radiative transfer code CMFGEN. To illustrate the significant improvements in spectral fitting achieved for photospheric phase Type II SN, and to document the effects associated with time dependence, we model the outer 6.1 M⊙ of ejecta of a BSG/RSG progenitor star....
