The Elusive Progenitors of Hydrogen-Poor Supernovae

Although we regularly observe stars exploding and dying throughout the Universe, frustratingly little is known about the progenitors of these events. This is especially true of hydrogen-poor supernovae, where pre-explosion imaging is typically not available. Just constraining simple properties such as the radius, mass, and the distribution and amount of radioactive material in the exploding star would go a long toward determining between different progenitor scenarios. I will describe ways in which we are constraining all of these properties from features of the supernova themselves and then discuss how it is impacting our understanding of the late stages of stellar evolution.
