    The Gaia-ESO Survey: Calibrating the lithium-age relation with open clusters and associations. I. Cluster age range and initial membership selections
    Context. Previous studies of open clusters have shown that lithium depletion is not only strongly age dependent but also shows a complex pattern with other...

    The Gaia-ESO Survey: Calibrating the lithium-age relation with open clusters and associations. II. Expanded cluster sample and final membership selection
    Context. The Li abundance observed in pre-main sequence and main sequence late-type stars is strongly age-dependent, but also shows a complex pattern depending...

    The Gaia-ESO Survey: Calibration strategy
    The Gaia-ESO survey (GES) is now in its fifth and last year of observations and has produced tens of thousands of high-quality spectra of stars in all Milky Way...

    The Gaia-ESO Survey: chemical signatures of rocky accretion in a young solar-type star
    It is well known that newly formed planetary systems undergo processes of orbital reconfiguration and planetary migration. As a result, planets or...

    The Gaia-ESO survey: Discovery of a spatially extended low-mass population in the Vela OB2 association
    The nearby (distance ~ 350-400 pc), rich Vela OB2 association, includes γ2 Velorum, one of the most massive binaries in the solar neighbourhood and an excellent...

    The Gaia-ESO Survey: Homogenisation of stellar parameters and elemental abundances
    The Gaia-ESO Survey is a public spectroscopic survey that targeted ≳10 5 stars covering all major components of the Milky Way from the end of 2011 to 2018...

    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: 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: 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...
