Query: Hot Evolved Stars in the Centers of M 31 and M 32   We present UV images of M 31 and M 32, as observed by HST with the
refurbished FOC. The galaxies were observed through the F175W and F275W
filters, allowing the construction of color magnitude diagrams (CMDs) for the
hundreds of detected sources found in each image. Comparison of these data with
the stellar evolutionary tracks of horizontal branch stars and their progeny
shows that for the first time outside of our own Galaxy, we may be measuring
the colors of individual stars that are evolving along post asymptotic giant
branch (PAGB), post-early AGB, and AGB-Manque' paths. Searching to the 6 sigma
detection limit, we find 1349 stars in M 31 and 183 stars in M 32. We compare
the distribution of stars in the CMDs with the expectations from theory.
