Supernovae of type II must be related to rather massive stars. They appear to occur rather exclusively in the spiral arms of galaxies and this fact alone sets a lower limit of about 5 M⊙ to their main sequence mass. If we believe that all massive stars above some critical value become supernovae (and none below this value) the supernova rate would ...
