    The Gaia-ESO Survey: Low-α element stars in the Galactic bulge
    We take advantage of the Gaia-ESO Survey iDR4 bulge data to search for abundance anomalies that could shed light on the composite nature of the Milky Way bulge...

    The Gaia-ESO Survey: Metallicity of the Chamaeleon I star-forming region
    Context. Recent metallicity determinations in young open clusters and star-forming regions suggest that the latter may be characterized by a slightly lower...

    The Gaia-ESO survey: Placing constraints on the origin of r-process elements
    Context. A renewed interest in the origin of r-process elements has been stimulated by the multi-messenger observation of the gravitational event GW170817, with...

    The Gaia-ESO Survey: processing FLAMES-UVES spectra
    The Gaia-ESO Survey is a large public spectroscopic survey that aims to derive radial velocities and fundamental parameters of about 105 Milky Way stars in the...

    The Gaia-ESO Survey: properties of newly discovered Li-rich giants
    Aims: We report 20 new lithium-rich giants discovered within the Gaia-ESO Survey, including the first Li-rich giant with an evolutionary stage confirmed by...

    The Gaia-ESO Survey: radial metallicity gradients and age-metallicity relation of stars in the Milky Way disk
    We study the relationship between age, metallicity, and α-enhancement of FGK stars in the Galactic disk. The results are based upon the analysis of high...

    The Gaia-ESO Survey: The analysis of high-resolution UVES spectra of FGK-type stars
    Context. The ongoing Gaia-ESO Public Spectroscopic Survey is using FLAMES at the VLT to obtain high-quality medium-resolution Giraffe spectra for about 105...

    The Gaia-ESO Survey: The analysis of the hot-star spectra
    Context. The Gaia-ESO Survey (GES) is a large public spectroscopic survey that has collected, over a period of six years, spectra of ~10 5 stars. This survey...

    The Gaia-ESO Survey: the chemical structure of the Galactic discs from the first internal data release
    Aims: Until recently, most high-resolution spectroscopic studies of the Galactic thin and thick discs were mostly confined to objects in the solar vicinity...
