Scientific paper

We report on our recent progress in modeling non-LTE central star atmospheres including blanketing by lines from the iron group elements. It is found that the spectroscopic analysis of the hottest stars (Teff approximately = 90,000 K) based on hydrogen Balmer and He II lines is hardly affected by metal opacities in the models. As a consequence, results from earlier analyses based on models composed of hydrogen and helium only remain essentially unchanged.
