Scientific paper

3C391 is a supernova remnant interacting with a molecular cloud, displaying a radio shell, X-ray bright interior, and mazer points. We propose a 65ks ACIS-S3 observation aiming to observe the source in arcsecond scales so as to reveal much clearer information on the interaction and on the progenitor than ROSAT and ASCA. The observation will yield X-ray fine structure, radial profile, and element distribution. This information will be used to confront cloud evaporation and breakout models for the emission and structure. We would answer whether the poorly resolved X-ray bridge-like structure relates to the breakout nozzle, what the NW sulphur arc is in nature, and why the NW abundance is subsolar. Also, we hope to find a compact stellar remnant of an inferred massive progenitor.
