Titans metal-poor reference stars II. Red giants and CEMP stars
Riano E. Giribaldi, Sophie Van Eck, Thibault Merle +6
Representative samples of F-, G-, K-type stars located out of the Solar Neighbourhood has started to be available in spectroscopic surveys. The fraction of metal-poor ([Fe/H]~$\les…
A neutron star candidate in the long-period binary 56 UMa
A. Escorza, D. Karinkuzhi, A. Jorissen +6
56 UMa is a wide binary system that contains a chemically peculiar red giant and a faint companion. Due to its surface chemical abundances, the red giant was classified as a barium…
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…
Observational evidence of third dredge-up occurrence in S-type stars with initial masses around 1 Msun
Shreeya Shetye, Stephane Goriely, Lionel Siess +3
Context- S stars are late-type giants with spectra showing characteristic molecular bands of ZrO in addition to the TiO bands typical of M stars. Their overabundance pattern shows…
The mass-ratio and eccentricity distributions of barium and S stars, and red giants in open clusters
Mathieu Van der Swaelmen, Henri M. J. Boffin, Alain Jorissen +1
In order to identify diagnostics distinguishing between pre- and post-mass-transfer systems, the mass-ratio distribution and period - eccentricity (P - e) diagram of barium and S s…
Gaia-ESO Survey: The analysis of pre-main sequence stellar spectra
A. C. Lanzafame, A. Frasca, F. Damiani +70
This paper describes the analysis of UVES and GIRAFFE spectra acquired by the Gaia-ESO Public Spectroscopic Survey in the fields of young clusters whose population includes pre-mai…
