| Abstract: The nature and role of the binary companion of carbon-oxygen white dwarf stars that explode as Type Ia supernovae (SNeIa) are not yet fully understood. Detections of circumstellar material (CSM) that contains hydrogen suggests that at least some have a non-degenerate companion. I will present the results of a recent NUV HST Snapshot survey of SNeIa sites which was designed to constrain the prevalence, location, and quantity of CSM in SNIa systems. In the future, this kind of targeted follow-up program will be automatically done by the Wide-Fast-Deep survey of the Large Synoptic Survey Telescope (LSST). In this talk I will also provide a status update of LSST construction, data management, commissioning plans, and ongoing activities regarding observing strategy, all with a focus on how they might enable future supernova science. |
