    The Gaia-ESO Survey: A globular cluster escapee in the Galactic halo
    A small fraction of the halo field is made up of stars that share the light element (Z ≤ 13) anomalies characteristic of second generation globular cluster (GC)...

    The Gaia-ESO Survey: A new diagnostic for accretion and outflow activity in the young cluster NGC 2264
    Context. NGC 2264 is a young cluster whose accretion properties can be investigated in detail by taking advantage of the FLAMES data in the context of the Gaia...

    The Gaia-ESO survey: A spectroscopic study of the young open cluster NGC 3293
    We present a spectroscopic analysis of the GIRAFFE and UVES data collected by the Gaia-ESO survey for the young open cluster NGC 3293. Archive spectra from the...

    The Gaia-ESO survey: Calibrating a relationship between age and the [C/N] abundance ratio with open clusters
    Context. In the era of large high-resolution spectroscopic surveys such as Gaia-ESO and APOGEE, high-quality spectra can contribute to our understanding of the...

    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...
