The Gaia-ESO Survey: processing of the FLAMES-UVES spectra
G. G. Sacco, L. Morbidelli, E. Franciosini +49
The Gaia-ESO Survey is a large public spectroscopic survey that aims to derive radial velocities and fundamental parameters of about 10^5 Milky Way stars in the field and in cluste…
The Gaia-ESO Survey: radial distribution of abundances in the Galactic disc from open clusters and young field stars
L. Magrini, S. Randich, G. Kordopatis +44
The spatial distribution of elemental abundances in the disc of our Galaxy gives insights both on its assembly process and subsequent evolution, and on the stellar nucleogenesis of…
First light observations of the solar wind in the outer corona with the Metis coronagraph
M. Romoli, E. Antonucci, V. Andretta +65
The investigation of the wind in the solar corona initiated with the observations of the resonantly scattered UV emission of the coronal plasma obtained with UVCS-SOHO, designed to…
The Gaia-ESO Survey: Extracting diffuse interstellar bands from cool star spectra, DIB-based interstellar medium line-of-sight structures at the kpc scale
L. Puspitarini, R. Lallement, C. Babusiaux +26
We study how diffuse interstellar bands (DIBs) measured toward distance-distributed target stars can be used to locate dense interstellar (IS) clouds in the Galaxy and probe a line…
The Gaia-ESO Survey: Projected Rotational Velocities of B stars in the Carina Nebula
W. Santos, S. Daflon, J. V. Sales Silva +19
The Carina Nebula is an active star-forming region with several open clusters rich in massive OB stars, thus making it an optimal target for studying stellar properties such as rot…
The Gaia-ESO Survey: the Galactic Thick to Thin Disc transition
A. Recio-Blanco, P. de Laverny, G. Kordopatis +36
(Abridged) We have used the atmospheric parameters, [alpha/Fe] abundances and radial velocities, determined from the Gaia-ESO Survey GIRAFFE spectra of FGK-type stars (iDR1), to pr…
The Gaia-ESO Survey: open clusters in Gaia-DR1 - a way forward to stellar age calibration
S. Randich, E. Tognelli, R. Jackson +42
We describe the methodologies that, taking advantage of Gaia-DR1 and the Gaia-ESO Survey data, enable the comparison of observed open star cluster sequences with stellar evolutiona…
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: Discovery of a spatially extended low-mass population in the Vela OB2 association
G. G. Sacco, R. D. Jeffries, S. Randich +28
The nearby (distance~350-400 pc), rich Vela OB2 association, includes $γ^2$ Velorum, one of the most massive binaries in the solar neighbourhood and an excellent laboratory for in…
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…
The Gaia-ESO Survey: The analysis of the hot-star spectra
R. Blomme, S. Daflon, M. Gebran +44
The Gaia-ESO Survey (GES) is a large public spectroscopic survey that has collected, over a period of 6 years, spectra of ~ 10^5 stars. This survey provides not only the reduced sp…
The Gaia-ESO Survey: Matching Chemo-Dynamical Simulations to Observations of the Milky Way
B. B. Thompson, C. G. Few, M. Bergemann +39
The typical methodology for comparing simulated galaxies with observational surveys is usually to apply a spatial selection to the simulation to mimic the region of interest covere…
New high resolution synthetic stellar libraries for the Gaia Mission
R. Sordo, A. Vallenari, J. C. Bouret +12
High resolution synthetic stellar libraries are of fundamental importance for the preparation of the Gaia Mission. We present new sets of spectral stellar libraries covering two sp…
The Gaia-ESO Survey: age spread in the star forming region NGC6530 from the HR diagram and gravity indicators
L. Prisinzano, F. Damiani, V. Kalari +33
In very young clusters, stellar age distribution is the empirical proof of the duration of star formation (SF) and of the physical mechanisms involved in the process. We derived ac…
The Gaia-ESO Survey: A lithium-rotation connection at 5 Myr?
J. Bouvier, A. Lanzafame, L. Venuti +37
We investigate here the lithium content of young low-mass stars in the 5~Myr-old star forming region NGC~2264 and its relationship with rotation. We combine lithium equivalent widt…
The Gaia-ESO Survey: Stellar content and elemental abundances in the massive cluster NGC 6705
T. Cantat-Gaudin, A. Vallenari, S. Zaggia +52
Chemically inhomogeneous populations are observed in most globular clusters, but not in open clusters. Cluster mass seems to play a key role in the existence of multiple population…
The Gaia-ESO Survey: Churning through the Milky Way
M. R. Hayden, A. Recio-Blanco, P. de Laverny +29
We attempt to determine the relative fraction of stars that have undergone significant radial migration by studying the orbital properties of metal-rich ([Fe/H]) stars within…
