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). |
