The complex stellar system M 22: confirming abundance variations with high precision differential measurements
M 22 (NGC 6656) is a chemically complex globular cluster-like system reported to harbour heavy element abundance variations.
M 22 (NGC 6656) is a chemically complex globular cluster-like system reported to harbour heavy element abundance variations. However, the extent of these variations and the origin of this cluster is still debated. In this work, we investigate the chemical inhomogeneity of M 22…
