Cluster target Giraffe HR15N RV precision
Listed in IVOA Registry (Virtual Observatory)
In the last 15 years different ground-based spectroscopic surveys have been started (and completed) with the general aim to deliver stellar parameters and elemental abundances for large samples of Galactic stars, complementing Gaia astrometry.
Description
Among those surveys, the Gaia-ESO Public Spectroscopic Survey, the only one performed on a 8m class telescope, was designed to target 100000 stars using FLAMES on the ESO VLT (both Giraffe and UVES spectrographs), covering all the Milky Way populations, with a special focus on open star clusters.
This article aims to provide an overview of the Survey implementation (observations, data quality, analysis and its success, data products and releases), of the open cluster survey, of the science results and potential, and of the survey legacy. A companion article (Gilmore et al., 2022A&A...666A.120G) reviews the overall Survey motivation, strategy, Giraffe pipeline data reduction, organisation and workflow. We make use of the information recorded and archived in: the observing blocks; during the observing runs; in a number of relevant documents; in the spectra and master catalogue of spectra; in the parameters delivered by the analysis nodes and the working groups; in the final catalogue; in the science papers.

Based on these, we critically analyse and discuss the output and products of the Survey, including science highlights. We also determined the average metallicities of the open clusters observed as science targets and of a sample of clusters whose spectra were retrieved from the ESO archive. The Gaia-ESO survey has determined homogeneous, good quality radial velocities and stellar parameters for a large fraction of its more than 110000 unique target stars.
Elemental abundances were derived for up to 32 elements for targets observed with UVES. Lithium abundances are delivered for about 1/3 of the sample. The analysis and homogenisation strategies have proven to be successful; several science topics have been addressed by the Gaia-ESO consortium and the community, with many highlight results achieved.
