N2 - We present a light-curve model for the super-Eddington luminosity phase of five classical novae observed with IUE. Optical and UV light curves are calculated based on the optically thick wind theory with a reduced effective opacity for a porous atmosphere. Fitting a model light curve with the UV 1455 Å light curve, we determine the white dwarf mass and distance to be 1.3 M⊙, 4.4 kpc for V693 CrA; 1.05 M⊙, 1.8 kpc for V1974 Cyg; 0.95 M⊙, 4.1 kpc for V1668 Cyg; 1.0 M ⊙, 2.1 kpc for V351 Pup; and 1.0 M⊙, 4.3 kpc for OS And.
