J/A+A/410/527       Abundances in the Galactic disk              (Bensby+, 2003)

Elemental abundance trends in the Galactic thin and thick disks as traced by nearby F and G dwarf stars Bensby T., Feltzing S., Lundstrom I. <Astron. Astrophys. 410, 527 (2003)> =2003A&A...410..527B
ADC_Keywords: Stars, nearby ; Abundances, peculiar Keywords: stars: fundamental parameters - stars: abundances - Galaxy: disk - Galaxy: formation - Galaxy: abundances - Galaxy: kinematics and dynamics Description: In table 3 we list all spectral lines that have been used in the determination of abundances. Column 1 gives the wavelength (in Angstrom), column 2 the lower excitation potential (in eV), column 3 the correction factor to the classical Unsoeld damping constant, and column 5 the radiation damping constant. An "S" in column 4 indicates that the broadening by collisions have been taken from Anstee & O'Mara (1995MNRAS.276..859A), Barklem & O'Mara (1997MNRAS.290..102B, 1998MNRAS.300..863B), and Barklem et al. (1998MNRAS.296.1057B, 2000, Cat. J/A+AS/142/467), instead of the classical Unsoeld broadening (indicated by a "U"). The solar abundance that is given for each element is the photospheric value from Grevesse & Sauval (1998SSRv...85..161G ). Column 6 gives our adopted log gf - values and column 7 the references. In table 6 we give the derived abundances for all individual elements (atoms and ions). The results for each star consist of three rows. The top row gives the mean abundance, the middle row gives the (1 sigma) standard deviation around the mean, and the third row gives the number of spectral lines that was used in computing the mean. All abundances are given relatively our solar values, which in turn is normalized to the standard photospheric values in Grevesse & Sauval (1998SSRv...85..161G ). File Summary:
