Abstract
A 48,000-sec observation of M31's central 34 arcmin, using the Rosat HRI, has led to the detection of 86 X-ray sources with luminosities above 1.4 x 10 exp 36 ergs/sec; of these, 18 sources are identified with globular clusters and two with SNRs. An extrapolation of the cumulative luminosity distribution to fainter luminosities indicates that only about 15-26 percent of the diffuse X-ray emission in the bulge is attributable to faint unresolved sources from this distribution. The spatial distribution and number density of X-ray sources in M31 appear to be very different from those of our Galaxy.
