| Abstract: |
Using a sample of 215 supernovae (SNe), we analyse their
positions relative to the spiral arms of their host galaxies,
distinguishing grand-design (GD) spirals from non-GD (NGD) galaxies.
Our results suggest that shocks in spiral arms of GD galaxies
trigger star formation in the leading edges of arms
affecting the distributions of core-collapse (CC) SNe (known to have
short-lived progenitors). The closer locations of SNe Ibc vs. SNe II
relative to the leading edges of the arms supports the belief
that SNe Ibc have more massive progenitors. SNe Ia having less massive
and older progenitors, show symmetric distribution
with respect to the peaks of spiral arms. |
