The Gaia-ESO Survey: chemical signatures of rocky accretion in a young solar-type star (2015)
Journal Article

It is well known that newly formed planetary systems undergo processes of orbital reconfiguration and planetary migration. As a result, planets or protoplanetary objects may accrete onto the central star, being fused and mixed into its external layer...

The Gaia-ESO Survey: empirical determination of the precision of stellar radial velocities and projected rotation velocities (2015)
Journal Article

Context. The Gaia-ESO Survey (GES) is a large public spectroscopic survey at the European Southern Observatory Very Large Telescope. Aims. A key aim is to provide precise radial velocities (RVs) and projected equatorial velocities (vsini) for repr...

A kinematically unbiased search for nearby young stars in the Northern hemisphere selected using SuperWASP rotation periods (2015)
Journal Article

We present a kinematically-unbiased search to identify young, nearby low-mass members of kinematic moving groups (MGs). Objects with both rotation periods shorter than 5 days in the SuperWASP All-Sky Survey and X-ray counterparts in the ROSAT All-Sky...

The Gaia-ESO Survey: A globular cluster escapee in the Galactic halo (2015)
Journal Article

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) stars. The ejected stars shed light on the formation of the Galactic halo by tracing the... Read More about The Gaia-ESO Survey: A globular cluster escapee in the Galactic halo.

The Gaia-ESO survey: Discovery of a spatially extended low-mass population in the Vela OB2 association (2015)
Journal Article

The nearby (distance ~ 350–400 pc), rich Vela OB2 association, includes ?2 Velorum, one of the most massive binaries in the solar neighbourhood and an excellent laboratory for investigating the formation and early evolution of young clusters. Recent... Read More about The Gaia-ESO survey: Discovery of a spatially extended low-mass population in the Vela OB2 association.

The Gaia-ESO Survey: CNO abundances in the open clusters Trumpler 20, NGC 4815, and NGC 6705 (2015)
Journal Article

Context. The Gaia-ESO Public Spectroscopic Survey will observe a large sample of clusters and cluster stars, covering a wide age-distance-metallicity-position-density parameter space. Aims. We aim to determine C, N, and O abundances in stars of Ga... Read More about The Gaia-ESO Survey: CNO abundances in the open clusters Trumpler 20, NGC 4815, and NGC 6705.
