Abundances of 12 metal-rich barium stars
Listed in IVOA Registry (Virtual Observatory)
We determined the atmospheric parameters and abundance pattern for a sample of metal-rich barium stars.
Description
We used high resolution optical spectroscopy. Atmospheric parameters and abundances were determined using the local thermodynamic equilibrium atmosphere models of Kurucz and the spectral analysis code MOOG.
We show that the stars have enhancement factors, [s/Fe], from 0.25 to 1.16. Their abundance pattern of Na, Al, {alpha}-elements and iron group elements as well as their kinematical properties are similar to the characteristics of the other metal rich and super metal-rich stars already analyzed. We conclude that metal rich barium stars do not belong to the bulge population.

We also show that metal rich barium stars are useful targets to probe the s-process enrichment in high metallicity environments.
