HD 11397 and HD 14282 - Two new barium stars?
L. Pompeia, D. M. Allen
We have performed a detailed abundance analysis of the content of s-process elements of two dwarf stars with suspected overabundace of those elements. Such stars belong to a specia…
Ruthenium and hafnium abundances in giant and dwarf barium stars
D. M. Allen, G. F. Porto de Mello
We present abundances for Ru and Hf, compare them to abundances of other heavy elements, and discuss the problems found in determining Ru and Hf abundances with laboratory gf-value…
Analysis of 26 Barium Stars II. Contributions of s-, r- and p-processes in the production of heavy elements
Dinah M. Allen, Beatriz Barbuy
Barium stars show enhanced abundances of the slow neutron capture (s-process) heavy elements, and for this reason they are suitable objects for the study of s-process elements. The…
Analysis of 26 Barium Stars I. Abundances
Dinah M. Allen, Beatriz Barbuy
We present a detailed analysis of 26 barium stars, including dwarf barium stars, providing their atmospheric parameters (Teff, log g, [Fe/H], vt) and elemental abundances. We aim a…
