The Gaia-ESO Survey: Abundance ratios in the inner-disk open clusters Trumpler 20, NGC 4815, NGC 6705
L. Magrini, S. Randich, D. Romano +50
Open clusters are key tools to study the spatial distribution of abundances in the disk and their evolution with time. Using the first release of stellar parameters and abundances…
The Gaia-ESO Survey: Reevaluation of the parameters of the open cluster Trumpler 20 using photometry and spectroscopy
P. Donati, T. Cantat-Gaudin, A. Bragaglia +34
Trumpler 20 is an old open cluster (OC) located toward the Galactic centre, at about 3 kpc from the Sun and 7 kpc from the Galactic centre. Its position makes this cluster pa…
iSpec: An integrated software framework for the analysis of stellar spectra
S. Blanco-Cuaresma, C. Soubiran, P. Jofré +1
iSpec is an integrated spectroscopic software framework suitable for the creation of spectral libraries such as the Benchmark Stars library and the determination of atmospheric par…
Gaia FGK Benchmark Stars and their reference parameters
Paula Jofre, Ulrike Heiter, Sergi Blanco-Cuaresma +1
In this article we summarise on-going work on the so-called Gaia FGK Benchmark Stars. This work consists of the determination of their atmospheric parameters and of the constructio…
Gaia FGK Benchmark Stars - Metallicity
Paula Jofre, U. Heiter, C. Soubiran +22
To calibrate automatic pipelines that determine atmospheric parameters of stars, one needs a sample of stars -- ``benchmark stars'' -- with well defined parameters to be used as a…
