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^\…
Gaia FGK Benchmark Stars: New Candidates At Low-Metallicities
Keith Hawkins, Paula Jofre, Ulrike Heiter +10
We have entered an era of large spectroscopic surveys in which we can measure, through automated pipelines, the atmospheric parameters and chemical abundances for large numbers of…
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…
An accurate and self-consistent chemical abundance catalogue for the APOGEE/Kepler sample
Keith Hawkins, Thomas Masseron, Paula Jofre +3
Context. The APOGEE survey has obtained high-resolution infrared spectra of more than 100,000 stars. Deriving chemical abundances patterns of these stars is paramount to piecing to…
The Gaia-ESO Survey: Sodium and aluminium abundances in giants and dwarfs - Implications for stellar and Galactic chemical evolution
R. Smiljanic, D. Romano, A. Bragaglia +40
Stellar evolution models predict that internal mixing should cause some sodium overabundance at the surface of red giants more massive than ~ 1.5--2.0 Msun. The surface aluminium a…
Identification of Globular Cluster Stars in RAVE data II: Extended tidal debris around NGC 3201
B. Anguiano, G. M. De Silva, K. Freeman +22
We report the identification of extended tidal debris potentially associated with the globular cluster NGC 3201, using the RAVE catalogue. We find the debris stars are located at a…
