  Double-lined spectroscopic binaries which are also eclipsing provide the most
accurate stellar data, and are consequently of first importance to improve
stellar evolution modelling. While the mass and radius of each component of
detached eclipsing binaries (EBs) can be accurately known, their temperature
Teff and chemical composition ([Fe/H]) are still uncertain. To contribute to
overcome these difficulties, we present metallicity-dependent Teff
determinations of 11 EBs (22 individual stars) from Stromgren synthetic
photometry. Inconsistencies suggesting new photometric observations are
discussed. Moreover, by exploring the best chi^2-fits to the photometric data,
we have re-derived their reddening.
