His own contributions to that history include supernova explosions in close binary systems as an origin for runaway OB stars (most pulsars are also high-velocity objects), and studies of expanding stellar associations that have prompted explanations in terms of supernovae.

The pre-explosion masses are derived from the lightcurves (types II and V) and from the absolute magnitude before the explosion (only for type V’s). We find mass ranges of 6 to 16 M.,

The Nearest Molecular Cloudsand are the small molecular-cloud component of the interstellar medium. The large internal velocity dispersions indicate that the clouds are not gravitationally bound, and that they have ages of ~ 10. yr.
