Chemical Compositions Of Red Giant Stars in the Old Open Cluster NGC 7789

Chemical Compositions Of Red Giant Stars in the Old Open Cluster NGC 7789

We have gathered optical-region spectra, derived model atmosphere parameters, and computed elemental abundances for 15 red giant stars in the open cluster NGC 7789. We focus on the light element group CNOLi that provides clues to evolutionary changes associated with internal fusion events and chemic...
