Abstract
We present an analysis of high resolution spectra in the far-UV - UV range (â¼905-2000Â Ã
) with non-LTE, spherical, hydrodynamical, line-blanketed models, of three O-type Galactic stars, and derive their photospheric and wind parameters. These data extend previously analyzed samples and fill a gap in spectral type coverage. The combined sample confirms a revised (downward) Teff scale with respect to canonical calibrations, as found in our previous works from UV and optical spectra, and in recent works by other authors.
