Not many people can say they have watched a star explode before their eyes, but David Sand can.On the evening of March 10, the astronomer happened to be on duty to monitor results coming in from an au...
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...

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...
Radio properties of supernova outbursts remain poorly understood despite longstanding campaigns following events discovered at other wavelengths. After ~ 30 years of observations, only ~ 50 supernovae...
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...
It may account for more than 80% of the matter in the universe and provide the "gravitational glue" that keeps galaxies together, but dark matter remains a mystery – despite tantalizing hints obtained...
Rapid Neutron Capture Process in Supernovae and Chemical Element Formation
Supernova—nucleosynthesis—abundance—r-process

The rapid neutron capture process (r-process) is one of the major nucleosynthesis processes responsible for the synthesis of heavy nuclei beyond iron. Isotopes beyond Fe are most exclusively formed in...
