    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: 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...
