Scientific paper

The use of Strömgren uvby photometry is proposed as a simple tool for the estimation of effective temperatures and metallicities in stars discovered to have planets. Previous photometric calibrations are tested with available spectroscopic measurements and their application to stars without high-resolution spectroscopy allowed the determination of metal abundances for 12 additional stars with planets. Their previously suggested relative metal-rich nature, when compared with similar field stars, is discussed as well as the possible relation of the stellar metal abundance with the mass of the planet.
