Italian scientists detect chemical anomalies in a low-mass globular cluster

(Phys.org)--Globular clusters have for a long time been considered as formed of stars with similar initial chemical composition, but recently, increasing evidence has emerged regarding their more complex nature. On Apr. 14, a team of Italian scientists led by Alessio Mucciarelli of the University of Bologna, has published a research paper describing chemical anomalies in the low-mass globular cluster NGC 6362, implying that globular clusters may be not as simple as previously thought.
