S stars and s-process in the Gaia era II. Constraining the luminosity of the third dredge-up with Tc-rich S stars
Shreeya Shetye, Sophie Van Eck, Alain Jorissen +6
S stars are late-type giants that are transition objects between M-type stars and carbon stars on the asymptotic giant branch (AGB). They are classified into two types: intrinsic o…
The Gaia-ESO Survey: detection and characterization of single line spectroscopic binaries
T. Merle, M. Van der Swaelmen, S. Van Eck +26
Recent and on-going large ground-based multi-object spectroscopic surveys allow to significantly increase the sample of spectroscopic binaries to get insight into their statistical…
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…
S stars and s-process in the Gaia era I. Stellar parameters and chemical abundances in a sub-sample of S stars with new MARCS model atmospheres
Shreeya Shetye, Sophie Van Eck, Alain Jorissen +6
S stars are transition objects between M-type giants and carbon stars on the asymptotic giant branch (AGB). They are characterized by overabundances of s-process elements. Roughly…
Cannibals in the thick disk: the young rich stars as evolved blue stragglers
P. Jofre, A. Jorissen, S. Van Eck +8
Spectro-seismic measurements of red giants enabled the recent discovery of stars in the thick disk that are more massive than 1.4 M_sun. While it has been claimed that most of thes…
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…
