Table 1: Physical quantities of the initial white dwarf models: mass, surface luminosity, central temperature, central density, radius and rotation velocity. The hot white dwarf model in the third row is only used for sequence TC (see Table 2).
Table 2: Properties of the computed model sequences. $\ensuremath {{M}_{\rm WD, init}}$ : initial mass, $\ensuremath{\dot{M}}$ : accretion rate, f: fraction of the Keplerian value of the accreted specific angular momentum (see Eq. (2)). $\dot{E}_{\rm diss}$ : rotational energy dissipation due to frictional heating. Yes (or No) means that this effect is considered (or not). $\ensuremath {\Delta M_{\rm He}}$ : accumulated helium mass until the helium ignition point. $T_{\rm c}$ and $\rho _{\rm c}$ : central temperature and density in the last computed model. $T_{\rm He}$ : maximum temperature in the helium envelope in the last computed model. $\rho _{\rm He}$ and $\eta _{\rm He}$ : density and degeneracy parameter at the position of the maximum temperature in the helium envelope in the last computed model. The last column indicates whether the model sequence will finally result in helium detonation or not.
