In recent years a wealth of new observational data has given astrophysicists an unprecedented look at the variety of outcomes that can arise from the collapse of the core of a massive star. With new observational techniques providing more data we have come to realize that there are many types of supernovae that arise from a stellar core-collapse. I will discuss how our picture of what happens when a stellar core collapses has evolved with time and the recent observational evidence that is leading us to this new viewpoint.
Prof. Swesty has been associated with astronomy at Stony Brook for more than twenty five years, initially as a graduate student and then, after 5 years at the University of Illinois, returning as a faculty member. He has studied core collapse supernovae, neutron stars, the behavior of neutron stars in close binary systems, and the properties of neutron star material.
