Ultra-Violet Radiation from Dwarf Nova Discs
Abstract
A review is given of dwarf-nova ultraviolet observations, based primarily on IUE data but with some ANS data. Dwarf novae are interacting binaries with orbital periods ranging from about 1.5 to about 15 hours. The disks in dwarf novae are the major source of ultraviolet light. The continuum is compared with several steady disk models, at quiescence and outburst. The results are discussed in terms of the mass accretion rates, and the time-dependent behavior of the continuum during the rise is presented.
