Spectroscopic and photometric evidence of two stellar populations in the Galactic globular cluster NGC 6121 (M 4)
Aims: We present abundance analysis based on high resolution spectra of 105 isolated red giant branch (RGB) stars in the Galactic Globular Cluster NGC 6121 (M 4). Our aim is to study its star population in the context of the multi-population phenomenon recently discovered to affect some Globular Clusters. Methods: The data have been collected with
