The Gaia-ESO Survey: the N/O abundance ratio in the Milky Way
L. Magrini, F. Vincenzo, S. Randich +31
The abundance ratio N/O is a useful tool to study the interplay of galactic processes, e.g. star formation efficiency, time-scale of infall and outflow loading factor We aim to tra…
Revisiting the science case for near-UV spectroscopy with the VLT
C. J. Evans, B. Barbuy, B. Castilho +8
In the era of Extremely Large Telescopes, the current generation of 8-10m facilities are likely to remain competitive at far-blue visible wavelengths for the foreseeable future. Hi…
The Gaia-ESO Survey: the origin and evolution of s-process elements
L. Magrini, L. Spina, S. Randich +45
Several works have found an increase of the abundances of the s-process neutron-capture elements in the youngest Galactic stellar populations, giving important constraints to stell…
The Gaia-ESO Survey: properties of newly discovered Li-rich giants
R. Smiljanic, E. Franciosini, A. Bragaglia +41
We report 20 new lithium-rich giants discovered within the Gaia-ESO Survey, including the first Li-rich giant with evolutionary stage confirmed by CoRoT data. Atmospheric parameter…
The Gaia-ESO survey: impact of extra-mixing on C- and N-abundances of giant stars
N. Lagarde, C. Reylé, A. C. Robin +30
The GES survey using FLAMES at the VLT has obtained high-resolution UVES spectra for a large number of giant stars, allowing a determination of the abundances of the key chemical e…
Deep secrets of intermediate-mass giants and supergiants: Models with rotation seem to overestimate mixing effects on the surface abundances of C, N, and Na
R. Smiljanic, P. Donati, A. Bragaglia +2
Recent observational results have demonstrated an increase in the surface Na abundance that correlates with stellar mass for red giants between 2 and 3 Msun. This trend supports ev…
