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...

2011/10/18
We improve estimates of stellar mass and mass-weighted average age of Type Ia supernova (SN Ia) host galaxies by combining UV and near-IR photometry with optical photometry in our analysis. Using 206 ...

We present the light curve analysis of late-type binary V523 Cas
for the season 2005. The spot has been revealed on the secondary. According to
theoretical considerations, the spot appeared to be ho...
