Distribution of supernovae relative to spiral arms and H II regions.
BARTUNOV O.S., TSVETKOV D.Y. and FILIMONOVA I.V.
Abstract (from CDS):
SNe of Types Ib and II show a strong concentration towards H II regions, while distribution of SNe Ia can be explained by chance superposition.
All studied distributions of SNe Ib and II show striking similarity, which suggests that their progenitors are massive stars with similar ages and initial masses. The association of SNe Ia with spiral arms suggests that their progenitors in spiral galaxies are likely to be intermediate mass stars.
