Chemical abundances and kinematics of a sample of metal-rich barium stars. Pereira C.B., Sales Silva J.V., Chavero C., Roig F., Jilinkski E. <Astron. Astrophys. 533, A51 (2011)> =2011A&A...533A..51P
ADC_Keywords: Stars, barium ; Abundances Keywords: stars: abundances - stars: chemically peculiar Abstract: We determined the atmospheric parameters and abundance pattern for a sample of metal-rich barium stars. 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, α-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. Description: The table contains equivalent width measurements for each individual line of the adopted line list, and the corresponding line parameters. The data analysed consist of FEROS@2.2m spectra of 12 barium stars. The resolution is of about R=45 000, which covers the range from 4500 to 9500Å, which include all the lines analysed. File Summary:
