Description
We derived consistent photospheric and wind parameters of O-type stars, by analyzing high-resolution spectra in the range 905 to 3250 Å with line-blanketed, hydrodynamic, non-LTE spherical models. We find significantly lower T[eff] and luminosities than previously assigned to these spectral types.
