The Type Ia Supernova Width-Luminosity Relation
Philip A. Pinto, Ronald G. Eastman
Observations of type Ia supernovae at high redshifts have become an important tool for studying the geometry of the universe. The relation between the duration of the peak phase of…

The Physics of Type Ia Supernova Lightcurves: I. Opacity and Diffusion
Philip A. Pinto, Ronald G. Eastman
We examine the basic physics of type Ia supernova (SNe Ia) light curves with a view toward interpreting the relations between peak luminosity, peak width, and late-time slope in te…

The Distances to Five Type~II Supernovae Using the Expanding Photosphere Method and the Value of
Brian P. Schmidt Robert P. Kirshner, Ronald G. Eastman, Mark M. Phillips +4
We have used observations gathered at CTIO to measure distances by the Expanding Photosphere Method (EPM) to 5 Type II supernovae. These supernovae lie at redshifts from cz = 1100…
