Abundance Anomalies in NGC6752 - Do AGB Stars Have a Role?

Campbell, S; Fenner, Y; Karakas, Amanda; Lattanzio, John; Gibson, Bradley K


We are in the process of testing a popular theory that the observed abundance anomalies in the Globular Cluster NGC 6752 are due to 'internal pollution' from intermediate mass asymptotic giant branch stars. To this end we are using a chemical evolution model incorporating custom-made stellar evolution yields calculated using a detailed stellar evolution code. By tracing the chemical evolution of the intracluster gas, which is polluted by two generations of stars, we are able to test the...[Show more]
