Exploring giant barium stars: ratio and elemental abundances of carbon, nitrogen, and oxygen
M. P. Roriz, N. A. Drake, N. Holanda +4
Barium (Ba) stars belong to binary systems that underwent mass transfer events. As a consequence, their envelopes were enriched with material synthesized in the interiors of their…
High-resolution spectroscopic analysis of four unevolved barium stars
M. P. Roriz, N. Holanda, L. V. da Conceição +4
A classical Local Thermodynamic Equilibrium analysis, based on high-resolution spectroscopic data, is performed for a sample of three potential barium dwarf candidates and one star…
Tungsten in barium stars
M. P. Roriz, M. Lugaro, S. Junqueira +3
Classical barium stars are red giants that received from their evolved binary companions material exposed to the \textit{slow} neutron-capture nucleosynthesis, i.e., the -proces…
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…
