Abundance Anomalies in NGC6752 - Do AGB Stars Have a Role?
S. W. Campbell, Y. Fenner, A. I. Karakas +2
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 asym…

On variations in the fine-structure constant and stellar pollution of quasar absorption systems
Y. Fenner, M. T. Murphy, B. K. Gibson
At redshifts z_abs < 2, quasar absorption-line constraints on space-time variations in the fine-structure constant, alpha, rely on the comparison of MgII and FeII transition wavele…
