TL;DR
OCCASO is a survey utilizing high-resolution spectroscopy from Spanish observatories to analyze chemical abundances in open clusters, aiming to understand the formation and evolution of the Galactic disc.
Contribution
It introduces a new survey targeting open clusters with high-resolution spectra to study Galactic disc evolution.
Findings
Chemical abundances derived for open clusters.
Insights into Galactic disc formation and evolution.
Establishment of a valuable open cluster chemical database.
Abstract
We present the motivation, design and current status of the Open Cluster Chemical Abundances from Spanish Observatories survey (OCCASO). Using the high resolution spectroscopic facilities available at Spanish observatories, OCCASO will derive chemical abundances in a sample of 20 to 25 open clusters older than 0.5 Gyr. This sample will be used to study in detail the formation and evolution of the Galactic disc using open clusters as tracers.
