Modeling of the Super-Eddington Phase for Classical Novae: Five IUE Novae
Abstract
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 light curve, we determine the white dwarf mass and distance to be (1.3 Msun, 4.4 kpc) for V693 CrA, (1.05 Msun, 1.8 kpc) for V1974 Cyg, (0.95 Msun, 4.1 kpc) for V1668 Cyg, (1.0 Msun, 2.1 kpc) for V351 Pup, and (1.0 Msun, 4.3 kpc) for OS And.
