Towards a photometric metallicity scale for open clusters
Original language description
Context. Open clusters are a useful tool when investigating several topics connected with stellar evolution; for example the age or distance can be more accurately determined than for field stars. However, one important parameter, the metallicity, is only known for a marginal percentage of open clusters. Aims. We aim at a consistent set of parameters for the open clusters investigated in our photometric Delta a survey of chemically peculiar stars. Special attention is paid to expanding our knowledge ofcluster metallicities and verifying their scale. Methods. Making use of a previously developed method based on normalised evolutionary grids and photometric data, the distance, age, reddening, and metallicity of open clusters were derived. To transform photometric measurements into effective temperatures to use as input for our method, a set of temperature calibrations for the most commonly used colour indices and photometric systems was compiled. Results. We analysed 58 open clusters in
