Stars: Abundances

Scientific paper

We present an abundance analysis for stars within 15 pc of the Sun located north of -30° declination. We have limited our abundance sample to absolute magnitudes brighter than +7.5 and have eliminated several A stars in the local vicinity. Our final analysis list numbers 114 stars. Unlike Allende Prieto et al. in their consideration of a very similar sample, we have enforced strict spectroscopic criteria in the determination of atmospheric parameters. Nevertheless, our results are very similar to theirs. We determine the mean metallicity of the local region to be <[Fe/H]>=-0.07 using all stars and -0.04 when interlopers from the thick disk are eliminated.
