		| Abstract: | We reconstruct the common envelope (CE) phase for the observed sample of
   white dwarf-main sequence post-common envelope binaries, with and without
   considering the internal energy of the progenitor giants' envelope. Using
   multi-regression analysis in the former case, we can model the CE
   ejection efficiency, αCE, in terms of the orbital period
   of the progenitor binary at the start of the CE phase. Considering the
   latter, αCE can be modelled in terms of the white dwarf
   mass. Finally, we compare our work with similar studies by Zorotovic et al. (2010) and De Marco et al. (2011). |
