Scientific paper

The theoretical light curves presently calculated on the basis of the delayed-detonation models of Khokhlov (1991) can accurately account for both the premaximum rise and postmaximum decline of the light curve; they also yield the correct maximum luminosity. The light-curve calculations employ: (1) an equation-of-state which gives attention to the ionization balance; (2) an implicit LTE radiation transport scheme whose space and time correction factors are derived from the radiation transport equation's exact solution at low optical depths; (3) time-dependent expansion opacities; (4) a gamma-ray deposition scheme; and (5) homologous expansion, to solve the structure of the models.
