Location: PSC 1136 (Conference room)
Speaker: Ori Fox (STScI)
Title: "Supernovae and their Progenitor Systems (or lack thereof)"

Despite the robust empirical supernova (SN) classification scheme in place, the underlying progenitor systems remain ambiguous for many subclasses. The most straightforward constraint relies on a detection of the progenitor star in high-resolution pre-explosion images. Such a direct identification is typically not feasible, however, even with modern telescopes such as Hubble. Instead, astronomers are forced to rely on supernova "forensics," where the surrounding circumstellar medium can yield direct clues about the mass loss from the star in the years leading up to the SN explosion. Although progenitor discussions have historically considered mostly single star systems, I will focus a significant portion of the discussion on the impact binary stars may have on our understanding of these results.
