Scientific paper

Procyon B is one of a select group of white dwarf stars that can be used to stringently test the fundamental physics of stellar degeneracy. We present our current analysis of HST STIS observations of this elusive white dwarf. Our spectra span 1800 - 10000 Angstroms. We detect carbon Swan bands, Mg II resonance lines and numerous iron features. Procyon B is therefore a rare DQZ white dwarf. Our model atmosphere analysis indicates a temperature of {7700+/-200}K. We discuss the implications of this result on the observational support for the white dwarf mass-radius relation.
