Abundances of red giants in open clusters

DOI

We have analysed high-resolution echelle spectra of red giant members for seven open clusters in the Galactic anticentre direction to explore their chemical compositions. Cluster membership has been confirmed by radial velocity. The spread in temperatures and gravities being very small among the red giants, nearly the same stellar lines were employed for all stars thereby reducing the abundance errors: the errors of the average abundance for a cluster were generally in the 0.02-0.05dex range. Our present sample covers Galactocentric distances of 8.3-11.3kpc and an age range of 0.2-4.3Gyr. A careful comparison of our results for the cluster NGC 2682 (M67) to other high-resolution abundance studies in the literature shows general good agreement for almost all elements in common.
