Selected properties of models computed by varying the values of the parameters affecting the mixing efficiency of rotation-induced instabilities (fμ, fc – models T1 and T2, respectively), the amount of angular momentum deposited by the accreted matter (fj model T3), and by assuming very high efficiency for the angular momentum transport (model T4).

Notes. Computations were performed for the third full cycle during the He-rich accretion phase ( = 0.7303 M⊙ – see Table 2). For the sake of comparison, we also report data for the standard case. The accreted mass ΔMacc, the mass of the He-rich zone with X(4He) > 0.1
, and the mass lost during the flash-driven RLOF ΔMlost are in 10−2 M⊙; the WD final mass after the RLOF episode
is in M⊙; the ignition density for He burning ρHe is in 105 g cm−3; the maximum temperature attained during the He-flash
is in 108 K; the maximum luminosity during the He-flash
is in 1012 L⊙; and the retention efficiency
.
