Sulfur abundances in three Galactic clusters: Ruprecht 106, Trumpler 5 and Trumpler 20
F. Lucertini, L. Monaco, E. Caffau +4
Context. Sulfur (S) is one of the lesser-studied -elements. Published investigations of its behavior have so far focused on local stars, and only a few clusters of the Milky Way…
Evolved eclipsing binary systems in the Galactic bulge: Precise physical and orbital parameters of OGLE-BLG-ECL-305487 and OGLE-BLG-ECL-116218
K. Suchomska, D. Graczyk, C. Gałan +17
Our goal is to determine, with high accuracy, the physical and orbital parameters of two double-lined eclipsing binary systems, where the components are two giant stars. We also ai…
Very metal-poor stars in the solar vicinity: age determination
Anastasiia Plotnikova, Giovanni Carraro, Sandro Villanova +1
The ages of the oldest and most metal-poor stars in the Milky Way bear important information on the age of the Universe and its standard model. We analyze a sample of 28 extremely…
Ca Triplet Metallicities and Velocities for twelve Globular Clusters towards the Galactic Bulge
D. Geisler, M. C. Parisi, B. Dias +6
Globular clusters (GCs) are excellent tracers of the formation and early evolution of the Milky Way. The bulge GCs (BGCs) are particularly important because they can reveal vital i…
The Gaia-ESO Public Spectroscopic Survey: Motivation, implementation, GIRAFFE data processing, analysis, and final data products
G. Gilmore, S. Randich, C. C. Worley +165
The Gaia-ESO Public Spectroscopic Survey is an ambitious project designed to obtain astrophysical parameters and elemental abundances for 100,000 stars, including large representat…
Investigating a predicted metallicity [Fe/H] variation in the Type II Globular Cluster NGC 362
C. Vargas, S. Villanova, D. Geisler +4
NGC 362 is a non-common Type II Galactic globular cluster, showing a complex pseudo two-color diagram or 'chromosome map'. The clear separation of its stellar populations in the co…
