A WISE-based search for debris discs amongst M-dwarfs in nearby, young, moving groups (2017)
Journal Article

We present a search for debris discs amongst M-dwarf members of nearby, young (5–150 Myr) moving groups (MGs) using infrared (IR) photometry, primarily from the Wide Infrared Survey Explorer (WISE). A catalogue of 100 MG M dwarfs that have suitable W... Read More about A WISE-based search for debris discs amongst M-dwarfs in nearby, young, moving groups.

The Gaia-ESO Survey: the inner disk, intermediate-age open cluster Trumpler 23 (2017)
Journal Article

Context. Trumpler 23 is a moderately populated, intermediate-age open cluster within the solar circle at a RGC ~ 6 kpc. It is in a crowded field very close to the Galactic plane and the color–magnitude diagram shows significant field contamination an...

The Gaia-ESO Survey: revisiting the Li-rich giant problem (2016)
Journal Article

The discovery of lithium-rich giants contradicts expectations from canonical stellar evolution. Here we report on the serendipitous discovery of 20 Li-rich giants observed during the Gaia-ESO Survey, which includes the first nine Li-rich giant stars...

The Gaia-ESO Survey: Lithium depletion in the Gamma Velorum cluster and inflated radii in low-mass pre-main-sequence stars (2016)
Journal Article

We show that non-magnetic models for the evolution of pre-main-sequence (PMS) stars cannot simultaneously describe the colour–magnitude diagram (CMD) and the pattern of lithium depletion seen in the cluster of young, low-mass stars surrounding ?2 Vel...

The Gaia-ESO Survey: Pre-Main Sequence Stars in the Young Open Cluster NGC 3293 (2016)
Journal Article

The young open cluster NGC3293 is included in the observing program of the Gaia-ESO survey (GES). The radial velocity values provided have been used to assign cluster membership probabilities by means of a single-variable parametric analysis. These m...

The Gaia-ESO Survey: A lithium-rotation connection at 5 Myr? (2016)
Journal Article

Context The evolution of lithium abundance in cool dwarfs provides a unique probe of nonstandard processes in stellar evolution. Aims We investigate the lithium content of young low-mass stars in the 5 Myr old, star forming region NGC 2264 and i... Read More about The Gaia-ESO Survey: A lithium-rotation connection at 5 Myr?.

The Gaia-ESO Survey: membership and initial mass function of the. Velorum cluster (2016)
Journal Article

Context. Understanding the properties of young open clusters, such as the initial mass function (IMF), star formation history, and dynamic evolution, is crucial for obtaining reliable theoretical predictions of the mechanisms involved in the star for...

The Gaia-ESO Survey: Dynamical analysis of the L1688 region in Ophiuchus (2016)
Journal Article

The Gaia ESO Public Spectroscopic Survey (GES) is providing the astronomical community with high-precision measurements of many stellar parameters including radial velocities (RVs) of stars belonging to several young clusters and star-forming regions...

The Gaia-ESO Survey: Stellar radii in the young open clusters NGC 2264, NGC 2547, and NGC 2516 (2016)
Journal Article

Context. Rapidly rotating, low-mass members of eclipsing binary systems have measured radii that are significantly larger than predicted by standard evolutionary models. It has been proposed that magnetic activity is responsible for this radius infla... Read More about The Gaia-ESO Survey: Stellar radii in the young open clusters NGC 2264, NGC 2547, and NGC 2516.

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...
