Abstract
We applied wavelength space binary spectral disentangling for a FEROS observation of HD 45166 and derived the atmospheric parameters of the binary components. Our results suggest a B7V-type companion in the system and prefer a lower mass solution for the quasi-WR primary than previous analyses, resembling a He-rich sdO star.
