Flare Stars as Age Indicators in Open Clusters

Abstract

A new set of isochrones derived from overshooting evolutionary models, allows one to give a homogeneous age determination for open clusters with solar chemical composition and in a range of age 4 107 ÷ 1.5 109 yr. In this context is derived an empirical new age calibration - absolute magnitude of the supposed brightest flare star in a cluster versus log age -. The evolutionary implication in finding or not finding flare stars in candidate open clusters is also examined.
