A partially cooled 0.8 M_☉ C-O dwarf has been made accrete C + O at several accretion rates. The computed models cover the full range of possible thermal behaviours found in accreting white dwarfs. Among the models lying in the range of accretion rates for which it occurs a central carbon ignition, one has been followed in detail also along the phase between central carbon ignition and the moment in which hydrostatic equilibrium is broken. The following dynamical evolution has been computed with a 1D hydrocode which includes a detailed computation of the synthesized elements. The bolometric light curves have also been produced. The results show that the computed models differ, in the light curves and in the relative abundance of the synthesized elements, by amounts that are compatible with the unhomogeneity which growing observational evidences suggest as existing in Type Ia Supernova events.
