Statistical-Equilibrium Model Atmospheres for Early-Type Stars. I. Hydrogen Continua
Abstract
Model atmospheres have been constructed for selected effective temperatures and gravities appropriate to early-type stars, allowing in an approximate way for deviations from LTE in the first ten bound states of hydrogen The essential approximation involved is the assumption of radiative detailed balance in the lines, which seems valid in the region of continuum formation. The resulting models are thought to be adequate for interpretation of the observed energy distribution of stars but cannot be used for discussions of line profiles We find that the deviations from LTE are quite small and that the predicted fluxes agree closely with those of LTE models.
