Barium stars as tracers of s-process nucleosynthesis in AGB stars II. Using machine learning techniques on 169 stars
J. W. den Hartogh, A. Yagüe López, B. Cseh +7
We aim to analyse the abundance pattern of 169 Barium (Ba) stars, using machine learning techniques and the AGB final surface abundances predicted by Fruity and Monash stellar mode…
High-resolution spectroscopic analysis of four new chemically peculiar stars
M. P. Roriz, C. B. Pereira, S. Junqueira +3
We present detailed chemical compositions of four stars on the first-ascent red giant branch that are classified as chemically peculiar, but lack comprehensive analyses at high spe…
Barium stars as tracers of s-process nucleosynthesis in AGB stars I. 28 stars with independently derived AGB mass
B. Cseh, B. Világos, M. P. Roriz +7
Barium (Ba) stars are polluted by material enriched in the slow neutron capture (s-process) elements synthesised in the interior of their former asymptotic giant branch (AGB) compa…
Heavy elements in barium stars
M. P. Roriz, M. Lugaro, C. B. Pereira +4
New elemental abundances for the neutron-capture elements Sr, Nb, Mo, Ru, La, Sm, and Eu are presented for a large sample of 180 barium (Ba) giant stars, a class of chemically pecu…
High-resolution spectroscopic observations of the new CEMP-s star CD-50776
M. Roriz, C. B. Pereira, N. A. Drake +2
Carbon enhanced metal poor (CEMP) stars are a particular class of low metalicity halo stars whose chemical analysis may provide important constrains to the chemistry evolution of t…
