An IUE Archival Study of the White Dwarf Temperature Variation in the Dwarf Nova WZ Sagittae

Sion, E. M.; Cheng, F. H.; Slevinsky, R. J. +2 more

The IUE archive offers a series of far UV spectra of ultra-short period dwarf nova WZ Sge over a long time baseline and hence the opportunity to monitor the ongoing accretion, the cooling of the white dwarf and temporal variations in the line spectra. We have carried out a quantitative analysis of these spectra including model atmosphere simulatio…
