Abstract

The simultaneous UBVR light curves presented by Horne, Wood, & Stiening (1991, ApJ, 378) are used to investigate the white dwarf and accretion disk in the dwarf nova HT Cas. For the white dwarf, log g = 8 and pure hydrogen model atmospheres are used to fit the UBVR fluxes, subject to the constraint that the models are consistent with the observed UV flux. A temperature T W = 14000 ± 1000 K and a distance D = 125 ± 8 pc for E(B-V) = 0.0 are found
