A SEARCH FOR YOUNG STARS IN THE HALO OF M31

Previous studies have identified young hot stars that appear to have b een formed in the halo of our Galaxy. Here we present preliminary resu lts of a spectroscopic search for similar objects in the halo of M31. Radial velocities have been measured for 23 apparently blue objects (s elected from APM measurements of Schmidt plates) in a magnitude range B(v) congruent-to 17-21. For one of these targets, AND 0029+413, the r adial velocity suggests that the object is gravitationally bound to M3 1 and hence that it may be in its halo. However, recent CCD photometry for this object indicates that it is redder than implied by the origi nal photographic observations. A number of possible scenarios are pres ented to explain this object, including one consistent with it being a young star in the halo of M31.
