J/A+A/454/895       Abundances of 26 barium stars. I.           (Allen+, 2006)

Analysis of 26 barium stars I. Abundances. Allen D.M., Barbuy B. <Astron. Astrophys. 464, 895 (2006)> =2006A&A...454..895A
ADC_Keywords: Stars, barium ; Stars, atmospheres ; Abundances Keywords: stars: chemically peculiar - stars: abundances Abstract: The abundances for Na, Al, alpha-, iron-peak, s-, and r-elements have been derived by using spectrum synthesis for a sample of 26 barium stars, including dwarf barium stars. High-resolution spectra were obtained with the FEROS spectrograph at the ESO-1.52m Telescope, along with photometric data with Fotrap at the Zeiss telescope at the LNA. Description: Table 5 shows the equivalent widths for Fe I and Fe II lines used to the fundamental parameters determination. Table 15 shows the lines, atomic constants, equivalent widths, and abundance results for the elements other than iron. File Summary:
