Fluorine abundance variations as a signature of enhanced extra mixing in red giants of the globular cluster M 4.

Abstract (from CDS):

We show that enhanced extra mixing in low-mass red giants can result in a fluorine abundance that is correlated with abundance variations of other elements participating in H burning, such as C, N, O, and Na. This finding is used to explain the fluorine abundance variations recently found in bright red giants of the globular cluster M4.
