Scientific paper

Low-resolution ultraviolet spectra of HE Del have been obtained with the IUE satellite. The continuum matches a high g stellar atmosphere with Teff ∼ 15,000 K, EB-V ∼ 0.2. However, the line spectrum contains resonance features of high ionization, with P Cygni profiles indicating outflow at more than 2300 km s-1 from the white dwarf. Possible changes and other line features are discussed. Mass loss is estimated to be in excess of 10-8 Msun yr-1.
