David Abstract Recent numerical models due to Grasberg and Nadexhin and to Morrison and Sartori of the light curve of supernovae of Types II and I are examined for their implications regarding presupernova evolutio and the nature of the supernova process. In these models an extremely extended envelope (radius r 1015 cm instead of r tO' cm considered by Colgate and \Vhite) for the presupernova is required. Suc] a structure is suggested by theoretical investigations of advanced stages of stellar evolution. Som hitherto inexplicable properties of supernovae of Types I and II can be explained. It is predicted tha presupernovae will be infrared sources of high luminosity, and that several may currently exist in th Galaxy.
