J/A+A/415/155       Oxygen abundances in the Galactic disk      (Bensby+, 2004)

Oxygen trends in the Galactic thin and thick disks. Bensby T., Feltzing S., Lundstrom I. <Astron. Astrophys. 415, 155 (2004)> =2004A&A...415..155B
ADC_Keywords: Abundances ; Equivalent widths Keywords: stars: fundamental parameters - stars: abundances - Galaxy: disk - Galaxy: formation - Galaxy: abundances - Galaxy: kinematics and dynamics Description: Oxygen abundances for the 72 program stars. Column one gives the Hipparcos number, columns 2-6 the derived oxygen abundances for the different indicators relative to the photospheric oxygen abundance ε(O)=8.83). Columns 7-11 give the abundances relative to our solar abundances, i.e. [O/H]=0 for all indicators. Columns 12-14 give the abundances for the triplet that have been corrected for NLTE effects according the the prescription in Gratton et al. (1999, Cat. J/A+A/350/955), and normalized to the new NLTE corrected abundance for the Sun. Column 15 gives the NLTE correction terms from Gratton et al. (1999, Cat. J/A+A/350/955) (GCEG) that were applied to the abundances in columns 12-14. Column 15 gives the empirical NLTE correction we determined (Eq. 1 in article. Columns 16-19 give the measured equivalent widths for the forbidden [OI] line at 636.3nm and the permitted oxygen triplet lines at 777nm. File Summary:
