A test field for Gaia. Radial velocity catalogue of stars in the South Ecliptic Pole
Y. Frémat, M. Altmann, E. Pancino +25
Gaia is a space mission currently measuring the five astrometric parameters as well as spectrophotometry of at least 1 billion stars to G = 20.7 mag with unprecedented precision. T…
The Gaia-ESO Survey: Lithium depletion in the Gamma Velorum cluster and inflated radii in low-mass pre-main-sequence stars
R. D. Jeffries, R. J. Jackson, E. Franciosini +25
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 d…
A Comparison of Stellar Elemental Abundance Techniques and Measurements
Natalie R. Hinkel, Patrick A. Young, Michael D. Pagano +15
Stellar elemental abundances are important for understanding the fundamental properties of a star or stellar group, such as age and evolutionary history, as well as the composition…
The Gaia-ESO survey: Hydrogen lines in red giants directly trace stellar mass
Maria Bergemann, Aldo Serenelli, Ralph Schoenrich +27
Red giant stars are perhaps the most important type of stars for Galactic and extra-galactic archaeology: they are luminous, occur in all stellar populations, and their surface tem…
Gaia FGK Benchmark Stars: New Candidates At Low-Metallicities
Keith Hawkins, Paula Jofre, Ulrike Heiter +10
We have entered an era of large spectroscopic surveys in which we can measure, through automated pipelines, the atmospheric parameters and chemical abundances for large numbers of…
The Gaia-ESO Survey: the selection function of the Milky Way field stars
E. Stonkute, S. E. Koposov, L. M. Howes +26
The Gaia-ESO Survey was designed to target all major Galactic components (i.e., bulge, thin and thick discs, halo and clusters), with the goal of constraining the chemical and dyna…
An accurate and self-consistent chemical abundance catalogue for the APOGEE/Kepler sample
Keith Hawkins, Thomas Masseron, Paula Jofre +3
Context. The APOGEE survey has obtained high-resolution infrared spectra of more than 100,000 stars. Deriving chemical abundances patterns of these stars is paramount to piecing to…
The Gaia-ESO Survey: Revisiting the Li-rich giant problem
A. R. Casey, G. Ruchti, T. Masseron +48
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 t…
The Gaia-ESO Survey: Sodium and aluminium abundances in giants and dwarfs - Implications for stellar and Galactic chemical evolution
R. Smiljanic, D. Romano, A. Bragaglia +40
Stellar evolution models predict that internal mixing should cause some sodium overabundance at the surface of red giants more massive than ~ 1.5--2.0 Msun. The surface aluminium a…
The Gaia-ESO Survey: membership and Initial Mass Function of the Gamma Velorum cluster
L. Prisinzano, F. Damiani, G. Micela +23
Understanding the properties of young open clusters, such as the Initial Mass Function (IMF), star formation history and dynamic evolution, is crucial to obtain reliable theoretica…
