Metallicities of Young Open Clusters I: NGC 7160 and NGC 2232

Published 5 Oct 2010 in astro-ph.SR | (1010.0739v1)

Abstract: We present a moderate-resolution spectroscopic analysis of the 10-25 Myr clusters NGC 7160 and NGC 2232, using observations obtained with the WIYN 3.5-m telescope. Both NGC 7160 and NGC 2232 are found to have super-solar metallicities, with a mean [Fe/H] = 0.16 \pm 0.03 (s.e.m.) for NGC 7160, and 0.22 \pm 0.09 (s.e.m.) or 0.32 \pm 0.08 for NGC 2232, depending on the adopted temperature scale. NGC 7160 exhibits solar distributions of Na, Fe-peak, and {\alpha}-elements. NGC 2232 is underabundant in light elements Al and Si, by ~0.25 and ~ 0.15 dex, respectively; [Ni/Fe] is roughly solar. The abundance of lithium in NGC 2232 stars is in agreement with undepleted values reported for other cluster main sequence stars. Our abundances are similar to other metal-rich open clusters and Galactic thin and thick disk stars.
