Old Open Clusters

Open clusters are among the best tracers of the Galactic disk properties (ages, distances, metallicities, etc. and their evolution in space and time). In this framework, we are working on a long term programme dedicated to the study of old Open Clusters. We are analyzing photometric and spectroscopic data for a fair sample of Open Clusters, with the intent of determining in a precise and homogeneous way their distances, ages, reddenings, and detailed chemical abundances.
