Gli ammassi aperti (AA) sono gruppi di stelle che condividono le stesse proprietà: età, distanza, composizione chimica. Sono i laboratori ideali per indagare una varietà di argomenti astrofisici: dall'evoluzione stellare a quella galattica. La missione Gaia e le survey spettroscopiche complementari hanno portato a una rivoluzione nella nostra conoscenza degli AA. Ma hanno bisogno di spettroscopia complementare ad alta risoluzione, R≥60000 e copertura di lunghezza d'onda maggiore, 400 a 900 nm. Questo è l'obiettivo de OCCASO che utilizzando FIES@NOT, HERMES@Mercator, CAFE@CAHA 2.2m (Spagna) e FIDEOS@ESO 1m (Cile) sta determinando velocità radiali, con una precisione di ~10 m s-1, e abbondanze chimiche, con incertezze di ~0,05 dex, che vengono usate come calibratori delle survey più ampie.

Open clusters (OCs) are groups of stars sharing the same general properties: age, distance, chemical composition. They are the ideal laboratories to investigate a variety of astrophysical topics: from stellar to Galactic evolution. The Gaia mission and the complementary ground-based spectroscopic surveys have led to a revolution in our knowledge of OCs. These surveys need complementary high-resolution, R≥60 000, spectroscopy with a larger wavelength coverage, e.g. 400 to 900 nm. This is the goal of OCCASO survey which using FIES@NOT, HERMES@Mercator, CAFE@CAHA 2.2m (Spain) and FIDEOS@ESO 1m (Chile) is determining accurate radial velocities, with a precision of ~10 m s-1, and chemical abundances, with uncertainties of ~0.05 dex, which are used as calibrators of the larger surveys.
