Radio and X-ray data shed light on the progenitor system of SN2011fe

January 8, 2012

We have recently submitted two manuscripts to ApJ describing our EVLA, Swift, and Chandra observations of the Type Ia SN2011fe, representing the deepest constraints on the non-thermal emission from such an explosion to date.  We use these data to characterize the properties of the circumbinary environment surrounding the progenitor star and constrain the nature of the putative donor star.  Check out the Publications page for details.
