Abstract
We present the results of the high resolution X-ray spectroscopy of hot white dwarfs, obtained with the 500 lines mm-1 Transmission Grating Spectrometer on EXOSAT. These data, which are unique in wavelength coverage, spectral resolution, and statistical quality, have offered us the first detailed look at the photospheric X-ray spectrum of these objects. The shape of the soft X-ray spectrum is highly sensitive to the spectral parameters; we use this sensitivity to derive accurate estimates of the effective temperature, surface gravity, and chemical composition of the atmosphere. Combining all available spectral data for these stars, from the optical to the X-ray band, a fully consistent description of the complete electromagnetic spectrum, in terms of a single model atmospheres spectrum, can be obtained.
