Add to ORKGWe 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
We discuss the observational evidences for the non-standard mixing that occurs in low mass stars whi...
