Scientific paper

An extensive grid of pure hydrogen model atmospheres for hot, high-gravity stars is presented. The models are intended to aid the analysis of visual, ultraviolet, and soft X-ray spectra of hot DA white dwarfs and EUV sources. The grid extends from log g equals 4.0(1.0)9.0 and T(eff) ranges from 20,000 K up to the Eddington limit for most surface gravities. Most of the models are LTE unblanketed calculations, but selected NLTE models and blanketed LTE models have also been computed in order to assess the importance of these effects. For each model, continuum fluxes are tabulated covering the entire range of wavelengths for which there is significant flux. Stromgren colors, UBV colors, and bolometric corrections are also given. Profiles and equivalent widths of the L-alpha, L-beta, L-gamma, H-alpha, H-beta, H-gamma, and H-delta lines are given as well.
