[17.22] Separating Binary Stars and Supernova Remnants at Three Sigma

K.K. Dyer (NRAO Socorro)

High spatial resolution X-ray observations are revealing a population of point-like nonvariable sources in a host of nearby galaxies. These are normally identified as supernova remnants or X-ray binaries. However, in general these detections do not have enough counts to fully populate a spectrum, leaving identifications extremely speculative. I will present simulated spectra from models and data from well studied Galactic remnants and binary systems in order to demonstrate the uncertainty inherent in identifying sources with only few hundred counts. I will also explore the efficacy of using a hardness ratio to distinguish between source types and the role of optical and radio observations in clearing up ambiguities.
