      abstract     = {M 31 is a large spiral galaxy that is located in close
                      proximity to our own Galaxy. The well known distance to it
                      and the moderate foreground absorption in its direction
                      makes it an ideal target for source population studies. Its
                      X-ray source population has been intensively studied by
                      XMM-Newton. Based on a recently published catalogue of UV
                      sources detected with AstroSat, we identified UV
                      counterparts of X-ray sources in the field of M 31 observed
                      with XMM-Newton. We investigated the UV colours and fitted
                      UV spectra with simple phenomenological models. In addition,
                      we used the X-ray spectral fits of the XMM2Athena project to
                      study the X-ray spectra and see how they evolve with time.We
                      discuss our results in terms of the different source
                      populations that can be identified in the field of M 31.},
