Contribution

It provides new observational data on open clusters from the Gaia-ESO Survey, enhancing understanding of the Galaxy's chemical evolution.

Findings

Preliminary radial metallicity gradient from open clusters.

Differences in chemical patterns across Galactic disk regions.

Initial 18-month observational results.

Abstract

The Gaia-ESO Survey (GES) is a large public spectroscopic survey that aims at observing with FLAMES@VLT the main stellar components of our Galaxy. The study of the population of open clusters is one of the main objectives of GES. We present some results from the first 18 months of observations, among them, a preliminary view of the radial metallicity gradient as traced by open cluster data and a comparison of the chemical patterns of clusters located in different parts of the Galactic disk.
