dc.descriptionDouble-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.
