The ultraviolet spectrum of the X-ray source 2A 0526-33.

Low resolution spectra of the X-ray source 2A0526-33 have been obtained with IUE. The X-ray source 2A0526-33 is confirmed as a cataclysmic variable from both its line and continuum ultraviolet spectra. Observed emission lines are similar to those found in other systems, such as EX Hya (Bath et al., 1980), AM Her or SS Cyg at quiescence (Fabbiano et al., 1980), and indicate a peculiar high velocity P Cygni profile for the C IV line. The observed weak ultraviolet interstellar absorption indicates a source closer than 500 pc. The continuum flux is consistent with a steady emission of an optically thick disk dominating at less than 2100 A, and a hot spot of temperature of about 9000 K contributing mostly in the optical. The hot spot could account for as much as 50 percent of the optical continuum flux, depending on the exact shape of the disk spectrum; the hot spot is not, however, fully modulated with the orbital period.
