The initial model is a 1.25 M_sun; C-O white dwarf (WD) and the accretion rate assumed is 10-11M_sun; yr-1. The accreted matter has normal composition (Z = 0.03). It is found that by the action of diffusion and convection some WD material is mixed into the accreted matter, raising the CNO mass fraction to Z ≈ 0.3. The resulting outburst resembles a fast nova eruption, with a peak bolometric luminosity of 2.9×105L_sun;, t3 = 25 days, an ejected mass of 6.5×10-6M_sun;, and a maximum velocity of 3800 km s-1.
