The Gaia-ESO Survey: Separating disk chemical substructures with cluster models
A. Rojas-Arriagada, A. Recio-Blanco, P. de Laverny +24
(Abridged) Recent spectroscopic surveys have begun to explore the Galactic disk system outside the solar neighborhood on the basis of large data samples. In this way, they provide…
Radii, masses, and ages of 18 bright stars using interferometry and new estimations of exoplanetary parameters
Roxanne Ligi, Orlagh Creevey, Denis Mourard +7
Accurate stellar parameters are needed in numerous domains of astrophysics. The position of stars on the H-R diagram is an important indication of their structure and evolution, an…
Chemical evolution of the inner 2 degrees of the Milky Way bulge: [alpha/Fe] trends and metallicity gradients
N. Ryde, M. Schultheis, V. Grieco +3
The structure, formation, and evolution of the Milky Way bulge is a matter of debate. Important diagnostics for discriminating between bulge models include alpha-abundance trends w…
The Gaia-ESO Survey: Characterisation of the [alpha/Fe] sequences in the Milky Way discs
G. Kordopatis, R. F. G. Wyse, G. Gilmore +30
We investigate, using the Gaia-ESO Survey internal Data-Release 2, the properties of the double sequence of the Milky Way discs (defined chemically as the high-alpha and low-alpha…
Understanding AGB evolution in Galactic bulge stars from high-resolution infrared spectroscopy
S. Uttenthaler, J. A. D. L. Blommaert, P. R. Wood +4
An analysis of high-resolution near-infrared spectra of a sample of 45 asymptotic giant branch (AGB) stars towards the Galactic bulge is presented. The sample consists of two subsa…
Young [/Fe]-enhanced stars discovered by CoRoT and APOGEE: What is their origin?
C. Chiappini, F. Anders, T. S. Rodrigues +34
We report the discovery of a group of apparently young CoRoT red-giant stars exhibiting enhanced [alpha/Fe] abundance ratios (as determined from APOGEE spectra) with respect to Sol…
