The Gaia-ESO Survey: Abundance ratios in the inner-disk open clusters Trumpler 20, NGC 4815, NGC 6705
L. Magrini, S. Randich, D. Romano +50
Open clusters are key tools to study the spatial distribution of abundances in the disk and their evolution with time. Using the first release of stellar parameters and abundances…
The Gaia-ESO Survey: Reevaluation of the parameters of the open cluster Trumpler 20 using photometry and spectroscopy
P. Donati, T. Cantat-Gaudin, A. Bragaglia +34
Trumpler 20 is an old open cluster (OC) located toward the Galactic centre, at about 3 kpc from the Sun and 7 kpc from the Galactic centre. Its position makes this cluster pa…
Revisited fluorine abundances in the globular cluster M22 (NGC 6656)
P. de Laverny, A. Recio-Blanco
Fluorine is a fairly good tracer of formation histories of multiple stellar populations in globular clusters as already revealed by several studies. Large variations in fluorine ab…
A Community Science Case for E-ELT HIRES
R. Maiolino, M. Haehnelt, M. T. Murphy +57
Building on the experience of the high-resolution community with the suite of VLT high-resolution spectrographs, which has been tremendously successful, we outline here the (scienc…
The RAdial Velocity Experiment (RAVE): Fourth data release
G. Kordopatis, G. Gilmore, M. Steinmetz +48
We present the stellar atmospheric parameters (effective temperature, surface gravity, overall metallicity), radial velocities, individual abundances and distances determined for 4…
The Gaia astrophysical parameters inference system (Apsis). Pre-launch description
C. A. L. Bailer-Jones, R. Andrae, B. Arcay +46
The Gaia satellite will survey the entire celestial sphere down to 20th magnitude, obtaining astrometry, photometry, and low resolution spectrophotometry on one billion astronomica…
Gaia FGK Benchmark Stars - Metallicity
Paula Jofre, U. Heiter, C. Soubiran +22
To calibrate automatic pipelines that determine atmospheric parameters of stars, one needs a sample of stars -- ``benchmark stars'' -- with well defined parameters to be used as a…
Fluorine abundances and the puzzle of globular cluster chemical history
P. de Laverny, A. Recio-Blanco
The abundance of fluorine in a few Galactic globular clusters is known to strongly vary from star-to-star. These unexpected chemical properties are an additional confirmation of th…
Through thick and thin: Structure of the Galactic thick disc from extragalactic surveys
G. Kordopatis, V. Hill, M. Irwin +7
We aim to understand the accretion history of the Milky Way by exploring the vertical and radial properties of the Galactic thick disc. We study the chemical and kinematic properti…
Characterisation of the Galactic thin disc with Corot targets
J. -C. Gazzano, G. Kordopatis, M. Deleuil +3
We use kinematical and chemical properties of 754 Corot stars to characterise the stellar populations of the Milky Way disc in three beams close the Galactic plane. From the atmosp…
