Post-CE evolution of the mass transfer rate (green dot-dashed line) with the orbital period for V1082 Sgr (left panel) and V479 And (right panel). The thick red cross indicates the properties at the moment the orbital period is the same as the observation. The purple line corresponds to the critical mass transfer rate Ṁ_stable above which hydrogen can burn steadily in a shell. The blue line corresponds to the maximum burning rate Ṁ_red-giant such that, for higher mass transfer rates, not all the transferred mass is accreted. The non-accreted mass piles up above the WD and is eventually lost from its vicinity in the form of fast winds similar to those of red giants. More details are provided in Sect. 5.
