TL;DR
This study precisely measured the elemental abundances of several key elements in Pleiades stars, confirming their near-solar metallicity with high-resolution spectroscopy, and validated methods against field stars.
Contribution
It provides a detailed and validated measurement of Pleiades metallicity using high-resolution spectra, refining previous estimates with improved accuracy.
Findings
Pleiades metallicity is approximately solar, [Fe/H] = +0.03.
Methodology validated with field star analysis.
Results align with previous measurements within uncertainties.
Abstract
We have measured the abundances of Fe, Si, Ni, Ti, and Na in 20 Pleiads with \teff values near solar and with low \vsini 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 \citet{Vale05}. Our result for the Pleiades is [Fe/H] = (statistical and systematic). The average of published measurements for the Pleiades is .
