Abstract: Presently, several types of compact binaries are known composed of a main sequence (MS) star and a white dwarf (WD), neutron star (NS), or black hole (BH) companion. The periods of most known compact binaries are in the range of hours to days. Currently it is not clear whether the tendency towards short periods is due to an observational bias or real. As such systems may expand our understanding of star formation and stellar evolution, we initiated a search for astrometric compact binaries in Stripe 82 of the Sloan Digital Sky Survey (SDSS). We concentrate on high proper motion stars with >100 mas/yr, among which we identified two sets of promising candidates. Here we report preliminary results of this project.
