Evolution of the mass-accretion rate of the WD (Ṁ₂, solid curve), mass-loss rate in the optically thick wind phase (Ṁ_wind, dashed curve, i.e., the phase from “A” to “B”) and mass growth rate of the WD (Ṁ_WD, dotted curve) as a function of time for the WD+MS channel (left-hand axis). The dot-dashed curve shows the evolution of the WD mass (right-hand axis). The vertical dashed curve again indicates the time of the explosion. The top panel gives an example where there is a delay between the production of the wind and the SN explosion, while the bottom panel corresponds to a model that is in the wind phase at the time of explosion.
