Scientific paper

The supernova 2005gj was just reported (CBET 302) to display the signatures of circumstellar interaction. This is only the second detection of hydrogen in the optical spectrum of a type Ia supernova. The interaction of SN ejecta with surrounding material should give rise to X-ray emission, as it does in core-collapse SNe. An observation with Chandra will measure the luminosity, thus determining the strength of the interaction. Very little is known about the progenitors of Ia SNe. Because the X-rays are a great probe of the circumstellar material around a SN, this Chandra observation could shed important light on the progenitor system.
