The s process in AGB stars as constrained by a large sample of Barium stars
B. Cseh, M. Lugaro, V. D'Orazi +8
Context. Barium (Ba) stars are dwarf and giant stars enriched in elements heavier than iron produced by the slow neutron-capture process (s process). They belong to binary systems…

Chemical abundances and kinematics of barium stars
D. B. de Castro, C. B. Pereira, F. Roig +4
In this paper we present an homogeneous analysis of photospheric abundances based on high-resolution spectroscopy of a sample of 182 barium stars and candidates. We determined atmo…
