As part of the Chandra Guaranteed Time Observations {GTO} program, we are searching M31 for x-ray transients. A complimentary GO program to study supersoft x-ray sources in M31 has recently been approved, and it will significantly expand our ability to find x-ray transients in M31. The x-ray properties of these transient sources {spectra, variability} allow us to determine whether the accreting object is a black hole or a neutron star. We propose HST observations of these x-ray transients to determine the nature of the mass-losing star. Massive stars will show little {<2 mag} change in their UV luminosities during outbursts, while low-mass stars will show large {>5 mag} changes in their UV luminosities. By determining the nature of the primary {accreting} and secondary stars in these x-ray transients, we will have the first dataset that will allow the evolution of black hole and neutron star binaries to be studied in an external galaxy. As >70 transients in the Milky Way {MW} contain black hole primaries, we expect that a major result will be an understanding of the formation of stellar mass black holes in another galaxy. Recent HST/DD observations of one M31 x-ray transient demonstrate that these observations are entirely feasible.
