The Impact of Bulges on the Radial Distribution of Supernovae in Disc
  Galaxies
  We present the results of the analysis of the impact of bulges on the radial
distributions of the different types of supernovae (SNe) in the stellar discs
of host galaxies with various morphologies. We find that in Sa-Sm galaxies, all
core-collapse (CC) and vast majority of SNe Ia belong to the disc, rather than
the bulge component. The radial distribution of SNe Ia in S0-S0/a galaxies is
inconsistent with their distribution in Sa-Sm hosts, which is probably due to
the contribution of the outer bulge SNe Ia in S0-S0/a galaxies. The radial
distributions of both types of SNe are similar in all the subsamples of Sa-Sbc
and Sc-Sm galaxies. These results confirm that the old bulges of Sa-Sm galaxies
are not significant producers of Type Ia SNe, while the bulge populations are
significant for SNe Ia only in S0-S0/a galaxies.
