The brightness distribution of the remnant of Tycho's Nova, which Baldwin has shown in Paper 56 (Figure 6), and the distance of 5000 pc determined by Menon and Williams (unpublished), establish beyond doubt a diameter of 10·8 pc and an average velocity of 13 300 km/sec. The initial velocity must have been higher.

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 ...
