The Gaia-ESO Survey: α-abundances of metal-poor stars
R. Jackson-Jones, P. Jofré, K. Hawkins +21
We performed a detailed study of the ratio of low-α to high-α stars in the Galactic halo as observed by the Gaia-ESO Survey. Using a sample of 381 metal-poor stars from the second…
The Gaia-ESO Survey: the most metal-poor stars in the Galactic bulge
L. Howes, M. Asplund, A. R. Casey +39
We present the first results of the EMBLA survey (Extremely Metal-poor BuLge stars with AAOmega), aimed at finding metal-poor stars in the Milky Way bulge, where the oldest stars s…
The Gaia-ESO Survey: metallicity of the Chamaeleon I star forming region
L. Spina, S. Randich, F. Palla +37
Context. Recent metallicity determinations in young open clusters and star-forming regions suggest that the latter may be characterized by a slightly lower metallicity than the Sun…
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: radial metallicity gradients and age-metallicity relation of stars in the Milky Way disk
M. Bergemann, G. Ruchti, A. Serenelli +42
We study the relationship between age, metallicity, and alpha-enhancement of FGK stars in the Galactic disk. The results are based upon the analysis of high-resolution UVES spectra…
