Description

The abundance inhomogeneities of light elements observed in globular clusters (GCs), and notably the ubiquitous Na-O anti-correlation, are generally interpreted as evidence that GCs comprise several generations of stars. There is an on-going debate as to the nature of the stars, which produce the inhomogeneous elements, and investigating the behavior of several elements is a way to shed new light on this problem. We aim at investigating the Li and Na content of the GC M4, that is known to have a well defined Na-O anti-correlation. We obtained moderate resolution (R=17000-18700) spectra for 91 main sequence (MS)/sub-giant branch stars of M4 with the Giraffe spectrograph at the FLAMES/VLT ESO facility. Using model atmospheres analysis we measured lithium and sodium abundances.
