A Sr-Rich Star on the Main Sequence of Omega Centauri [PDF]

, 2006
Abundance ratios relative to iron for carbon, nitrogen, strontium and barium are presented for a metal-rich main sequence star ([Fe/H]=--0.74) in the globular cluster omega Centauri. This star, designated 2015448, shows depleted carbon and solar nitrogen,

Analysis of 26 Barium Stars II. Contributions of s-, r- and p-processes in the production of heavy elements

, 2006
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.
