Unlike the typical globular clusters, the stars of Omega Centauri do not show the same metal content, a parameter that indicates its age, but a large range in it. A team of scientists from the Indian Institute of Astrophysics (IIA) studied numerous stars of this cluster and discovered Helium (He) enhanced cool bright stars among the metal-rich sample of Omega Centauri. This result, based on a spectroscopic survey of the  cluster, determines the He-abundance of these stars for the first time. The study provides a very important clue for the origin of the He-enhanced population establishing that these are the second generation of stars formed from the metal-rich and He-enhanced material from the first generation of stars. And, also that the He-enhanced main-sequence stars evolve to the metal-rich He-enhanced cool bright stars.
