| dc.description.abstractEn | Open Clusters (OCs) are very good laboratories to test theories of stellar evolution. They have also been widely used as tracers of the formation and evolution of the Galactic disk. Nearby OCs with different ages and metallicities are commonly used as benchmark objects for galactic and stellar studies because high precision measurements are usually achievable. We aim to perform a detailed study of ∼30 nearby (closer than 500 pc) and old (age>300 Myr) OCs. Thanks to Gaia DR2, accurate memberships, distances, motions and ages are available for a large amount of OCs, allowing us to revise their physical properties. Here we show the preliminary results of the strictly line-by-line differential abundances of three targets: the Hyades, NGC 2632 (Praesepe) and Ruprecht 147. | |
