Scientific paper

Theoretical relations are derived expressing the energy E of a type II supernova outburst, the mass M of the ejected envelope, and the presupernova radius R in terms of the duration of the light-curve plateau and the corresponding absolute magnitude and photospheric velocity. For typical supernovae, E is approximately equal to 6 x 10 to the 5th erg, M is approximately equal to 6 solar masses, and R is appoximately equal to 1000 solar radii; for SN 1969l in NGC 1068, E is approximately equal to 10 to the 51st erg, M is approximately equal to 10 solar masses, and R is approximately equal to 500 solar radii.
