Abstract

We present a detailed Monte Carlo simulator of the Galactic population of binary stars. Preliminary results are presented for the white dwarf-main sequence (WD+MS) binary population resulting from a common envelope (CE) episode. We also study the effects of the observational selection criteria on different color-color diagrams, for different binding energy parameters, γ, and common envelope efficiencies, αCE. Finally, we also compare our results with the identified population of white dwarf-main sequence binaries in the SDSS.
