Scientific paper

The rates of SN Ia for double-degenerate and single-degenerate scenario are computed for the models of spiral and elliptical galaxies. The number of nuclearly burning white dwarfs (NBWD) is traced. The data favours double-degenerate scenario and suggests lower number of NBWD per unit mass in ellipticals and their lower average mass as one of the reasons for the difference in the number of supersoft X-ray sources observed in the galaxies of different types.
