NGC 6522: A typical globular cluster in the galactic bulge without signatures of rapidly rotating population III stars

Ness, M; Asplund, Martin; Casey , A R

Description

We present an abundance analysis of eight potential member stars of the old Galactic bulge globular cluster NGC 6522. The same stars have previously been studied by Chiappini et al., who found very high abundances of the slow neutron capture elements compared with other clusters and field stars of similar metallicity, which they interpreted as reflecting nucleosynthesis in rapidly rotating, massive Population III stars. In contrast to their analysis, we do not find any unusual enhancements of...[Show more]
