Supernova Progenitors and Their Binary Companions
Schuyler D. Van Dyk
2. The search for the binary companions of SN progenitors in SNRs
It is absolutely essential to determine the stellar origins of supernovae, i.e., their progenitors or progenitor systems. I will briefly review what we know about the progenitors of supernovae beyond the Local Group from their direct identification in high spatial resolution pre-explosion images, primarily obtained with the Hubble Space Telescope. I will also touch on attempts to recover a surviving companion in core-collapse progenitor binary systems, particularly for the stripped-envelope supernovae, and the implications from these searches.
