Gaia Benchmark stars and their twins in the Gaia-ESO Survey
Paula Jofre
The Gaia benchmark stars are stars with very precise stellar parameters that cover a wide range in the HR diagram at various metallicities. They are meant to be good representative…
Using chemical tagging to redefine the interface of the Galactic disk and halo
Keith Hawkins, Paula Jofre, Thomas Masseron +1
We present a chemical abundance distribution study in 14 , odd-Z, even-Z, light, and Fe-peak elements of approximately 3200 intermediate metallicity giant stars from the APOGEE…
Gaia FGK benchmark stars: abundances of alpha and iron-peak elements
P. Jofré, U. Heiter, C. Soubiran +26
In the current era of large spectroscopic surveys of the Milky Way, reference stars for calibrating astrophysical parameters and chemical abundances are of paramount importance. We…
Gaia FGK Benchmark Stars: Effective temperatures and surface gravities
U. Heiter, P. Jofré, B. Gustafsson +3
Large Galactic stellar surveys and new generations of stellar atmosphere models and spectral line formation computations need to be subjected to careful calibration and validation…
The Gaia-ESO Survey: Empirical determination of the precision of stellar radial velocities and projected rotation velocities
R. J. Jackson, R. D. Jeffries, J. Lewis +58
The Gaia-ESO Survey (GES) is a large public spectroscopic survey at the European Southern Observatory Very Large Telescope. A key aim is to provide precise radial velocities (RVs)…
The Gaia-ESO Survey: Insights on the inner-disc evolution from open clusters
L. Magrini, S. Randich, P. Donati +37
Context. The inner disc, linking the thin disc with the bulge, has been somehow neglected in the past because of intrinsic difficulties in its study, due, e.g., to crowding and hig…
Kinematics and chemistry of recently discovered Reticulum 2 and Horologium 1 dwarf galaxies
Sergey E. Koposov, Andrew R. Casey, Vasily Belokurov +17
Photometry alone is not sufficient to unambiguously distinguish between ultra-faint star clusters and dwarf galaxies because of their overlap in morphological properties. Here we r…
The Gaia-ESO Survey: Detailed Abundances in the Metal-poor Globular Cluster NGC 4372
I. San Roman, C. Muñoz, D. Geisler +28
We present the abundance analysis for a sample of 7 red giant branch stars in the metal-poor globular cluster NGC 4372 based on UVES spectra acquired as part of the Gaia-ESO Survey…
The Gaia-ESO Survey: a quiescent Milky Way with no significant dark/stellar accreted disc
G. R. Ruchti, J. I. Read, S. Feltzing +26
According to our current cosmological model, galaxies like the Milky Way are expected to experience many mergers over their lifetimes. The most massive of the merging galaxies will…
The Gaia-ESO Survey: A globular cluster escapee in the Galactic halo
K. Lind, S. E. Koposov, C. Battistini +37
A small fraction of the halo field is made up of stars that share the light element (Z<=13) anomalies characteristic of second generation globular cluster (GC) stars. The ejected s…
The Gaia-ESO Survey: Tracing interstellar extinction
M. Schultheis, G. Kordopatis, A. Recio-Blanco +19
Large spectroscopic surveys have enabled in the recent years the computation of three-dimensional interstellar extinction maps thanks to accurate stellar atmospheric parameters and…
The Gaia-ESO Survey: Discovery of a spatially extended low-mass population in the Vela OB2 association
G. G. Sacco, R. D. Jeffries, S. Randich +28
The nearby (distance~350-400 pc), rich Vela OB2 association, includes Velorum, one of the most massive binaries in the solar neighbourhood and an excellent laboratory for inv…
