The extreme chemistry of multiple stellar populations in the metal-poor globular cluster NGC 4833

E. Carretta, A. Bragaglia, R. G. Gratton +7

Our FLAMES survey of Na-O anticorrelation in globular clusters (GCs) is extended to NGC 4833, a metal-poor GC with a long blue tail on the horizontal branch (HB). We present the ab…
