Analysis of UV spectra of white dwarfs in binary systems

Ultraviolet spectra of hot white dwarfs provide a window for the study of white dwarf atmospheres which are outshone in the optical spectrum. The analysis of FUSE spectra of white dwarfs in binary systems will be presented. By using the available models, the temperature, surface gravity and chemical composition will be determined. In addition, the observed photospheric lines in the FUSE spectra are used to trace the orbital path of the white dwarf and hence place constraints on the binary parameters.
