dc.description.abstractEnGalactic Open Clusters (OCs) are crucial to investigate the formation and evolution of the Galactic disc. The Open Clusters Chemical Abundance from Spanish Observatory survey (OCCASO) aims to provide high precision radial velocity (typical uncertainties between 100 to 200 m/s) and to determine abundances for more than 20 chemical species in around 30 Northern OCs (Casamiquela et al, 2016). We use high resolution (R > 65,000) high signal-to-noise (˜70) spectra of at least 6 Red Clump stars for each cluster. In this work we combined Gaia DR2 mean parallaxes and proper motions, and OCCASO radial velocities to obtain 3D spatial velocities and determine the orbits of the clusters. We also study Galactic trends with Galactocentric radius and age of Fe peak and alpha elements for the 18 OCs currently observed in the OCCASO survey, and we compare them with chemo-dynamical models of the Milky Way.
