Title:  Gaia-ESO Survey: the first release from the analysis of UVES spectra of FGK-type stars

The Gaia-ESO Survey is an ambitious public spectroscopic survey that is observing more than 100000 stars with the FLAMES multi-fiber facility at the VLT. High-resolution (R ~ 47000) UVES spectra is being obtained for a sample of about 5000 FGK-type stars. The stars are mainly FG-type dwarfs in the solar neighborhood (within 2 kpc) and clump giants in a sample of old and intermediate-age open clusters. Some giants in the bulge, and in the inner and outer regions of the disk are also observed. The first public release of advanced data products is expected for mid-2014. Results from the analysis of the UVES spectra will include atmospheric parameters and abundances for about 20 different elements for more than 1500 stars. This sample of high-resolution spectra of FGK-type stars is among the largest ones of its kind analyzed in a homogeneous way. In this presentation, I will introduce the Survey and its goals, with emphasis on the analysis of UVES spectra of FGK-type stars. I will discuss the analysis of the spectra and the data products that will be made available to the community in public releases. Finally, I will also present some examples of early science results obtained with Gaia-ESO data.
