Rotation and Activity in the Solar-Metallicity Open Cluster NGC 2516**Based on observations obtained at the Anglo-Australian Telescope and on observations obtained at the Cerro Tololo Inter-American Observatory, NOAO, which is operated by the Associated Universities for Research in Astronomy (AURA), Inc., under cooperative agreement with the National Science Foundation.

We report new measures of radial velocities and rotation rates (v sin i) for 51 F and early G stars in the open cluster NGC 2516 and combine these with previously published data. From high signal-to-noise ratio spectra of two stars, we show that NGC 2516 has a relative iron abundance with respect to the Pleiades of Δ[Fe/H] = +0.04 ± 0.07 at the canonical reddening of E(B-V) = 0.12, in contrast to previous photometric studies that placed the …
