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…
Binary interaction along the Red Giant Branch: The Barium Star perspective
Ana Escorza, Lionel Siess, Drisya Karinkuzhi +3
Barium (Ba) stars form via mass-transfer in binary systems, and can subsequently interact with their white dwarf companion in a second stage of binary interaction. We used observat…
When binaries keep track of recent nucleosynthesis: The Zr - Nb pair in extrinsic stars as an s-process diagnostic
D. Karinkuzhi, S. Van Eck, A. Jorissen +9
Barium stars are s-process enriched giants. They owe their chemical peculiarities to a past mass transfer phase. During which they were polluted by their binary companion, which at…
Chemical analysis of three barium stars: HD 51959, HD 88035, HD 121447
Drisya Karinkuzhi, Aruna Goswami, Navin Sridhar +3
We present elemental abundance results from high resolution spectral analysis of three nitrogen-enhanced barium stars. The analysis is based on spectra obtained with the FEROS atta…
