Shocking Results About Exploding Stars
Abstract
Early light curves of supernovae are dominated by the emission of surface material that has been heated and ejected by the supernova shock. Studying this shock cooling can provide unique constraints on the radius of the progenitor, which is important for comparisons to stellar modeling, populations of massive stars, and pre-explosion imaging. Here I summarize both numerical and semi-analytic work to model this phase and apply it to current and future observations. I discuss a wide range of events, from the fairly common Type IIP supernovae to the exotic Type I superluminous supernovae for which their exact progenitors are still elusive.
