Tracing the evolution of NGC 6397 through the chemical composition of its stellar populations

Lind, Karin; Charbonnel, C; Decressin, T; Primas, Francesca; Grundahl, Frank; Asplund, Martin


Context. The chemical compositions of globular clusters provide important information on the star formation that occurred at very early times in the Galaxy. In particular the abundance patterns of elements with atomic number z = 13 may shed light on the properties of stars that early on enriched parts of the star-forming gas with the rest-products of hydrogen-burning at high temperatures. Aims.We analyse and discuss the chemical compositions of a large number of elements in 21 red giant branch...[Show more]
