TitleHelium and multiple populations in the massive globular cluster NGC 6266 (M 62)
AbstractRecent studies suggest that the helium content of multiple stellar populations in globular clusters is not uniform. The range of helium varies from cluster to cluster with more massive GCs having, preferentially, large helium spread. GCs with large helium variations also show extended-blue horizontal branch. I exploit Hubble Space Telescope photometry to investigate multiple stellar populations in NGC 6266 and infer their relative helium abundance (...) The comparison between NGC 6266 and other GCs hosting helium-enriched stellar populations supports the presence of a correlation among helium variations, cluster mass, and HB extension.
