On Identifying the Progenitors of Type Ia Supernovae
Identifying Progenitors Type Supernovae
2011/10/20
We propose two new means of identifying the main class of progenitors of Type Ia supernovae--single or double degenerate: (i) If the range of supernova properties is significantly determined by the ra...
Velocity Evolution and the Intrinsic Color of Type Ia Supernovae
Velocity Evolution Intrinsic Colo Type Ia Supernovae
2011/10/11
To understand how best to use observations of Type Ia supernovae (SNe Ia) to obtain precise and accurate distances, we investigate the relations between spectra of SNe Ia and their intrinsic colors. U...
We present an analysis of the B-band and V-band rise-time distributions of nearby Type Ia supernovae (SNe Ia). We use a two-stretch template-fitting method to measure the rise and decline of BV light ...
Confronting 2D delayed-detonation models with light curves and spectra of Type Ia supernovae
supernovae: general
2011/9/26
We compare models for Type Ia supernova (SN Ia) light curves and spectra with an extensive set of observations. The models come from a recent survey of 44 two-dimensional delayed-detonation models com...
