Metallicities of open clusters NGC7160 and NGC2232

Both NGC 7160 and NGC 2232 are found to have super-solar metallicities, with a mean [Fe/H]=0.16+/-0.03(s.e.m.) for NGC 7160, and 0.22+/-0.09(s.e.m.) or 0.32+/-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 ~0.15dex, 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.
