On the metallicity dependance of the [Y/Mg] - age relation for solar type stars

S. Feltzing, L. M. Howes, P. J. McMillan +1

Several recent studies of Solar twins in the Solar neighbourhood have shown a tight correlation between various elemental abundances and age, in particular [Y/Mg]. If this relation…

CNO abundances and carbon isotope ratios in evolved stars of the open clusters NGC 2324, NGC 2477, and NGC 3960

Grazina Tautvaisiene, Arnas Drazdauskas, Angela Bragaglia +2

Our main aim is to determine carbon-to-nitrogen and carbon isotope ratios for evolved giants in the open clusters NGC 2324, NGC 2477, and NGC 3960, which have turn-off masses of ab…

The AMBRE Project: Constraining the lithium evolution in the Milky Way

G. Guiglion, P. de Laverny, A. Recio-Blanco +5

The chemical evolution of lithium in the Milky Way represents a major problem in modern astrophysics. Indeed, lithium is, on the one hand, easily destroyed in stellar interiors, an…

The Gaia-ESO survey: Metal-rich bananas in the bulge

Angus A. Williams, N. W. Evans, Matthew Molloy +25

We analyse the kinematics of giant stars in the direction of the Galactic bulge, extracted from the Gaia-ESO survey in the region $-10^\circ \lesssim \ell \lesssim 10^\…

The Gaia-ESO Survey: Probes of the inner disk abundance gradient

H. R. Jacobson, E. D. Friel, L. Jilkova +41

The nature of the metallicity gradient inside the solar circle (R_GC < 8 kpc) is poorly understood, but studies of Cepheids and a small sample of open clusters suggest that it stee…

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…
