Iron-peak elements Sc, V, Mn, Cu and Zn in Galactic bulge globular clusters

H. Ernandes, B. Barbuy, A. Alves-Brito +3

Globular clusters are tracers of the history of star formation and chemical enrichment in the early Galaxy. Their abundance pattern can help understanding their chemical enrichment…

Elemental abundances and classification of CEMP stars

Dinah M. Allen, Sean G. Ryan, Silvia Rossi +2

We present a detailed study of Carbon-Enhanced Metal-Poor (CEMP) stars, based on high-resolution spectroscopic observations of a sample of 18 stars. The stellar spectra for this sa…

Mn, Cu and Zn abundances in barium stars and their correlations with neutron capture elements

Dinah M. Allen, Gustavo F. Porto de Mello

We present abundances of Mn, Cu, Zn and various light and heavy elements for a sample of barium and normal giant stars, and present correlations between abundances contributed to d…

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…
