Abstract

We have measured the abundances of Fe, Si, Ni, Ti, and Na in 20 Pleiades stars with T eff values near solar and with low vsin i using high-resolution, high signal-to-noise echelle spectra. We have validated our procedures by also analyzing 10 field stars of a range of temperatures and metallicities that were observed by Valenti and Fischer. Our result for the Pleiades is [Fe/H] = +0.03 ± 0.02 ± 0.05 (statistical and systematic). The average of published measurements for the Pleiades is +0.042 ± 0.021.
