A JWST project on 47 Tucanae. Binaries among multiple populations
A. P. Milone, A. F. Marino, M. Bernizzoni +25
Almost all globular clusters (GCs) contain multiple populations consisting of stars with varying helium and light-element abundances. These populations include first-population sta…

Hubble Space Telescope survey of Magellanic Cloud star clusters. Binaries among the split main sequences of NGC 1818, NGC 1850, and NGC 2164
F. Muratore, A. P. Milone, F. D'Antona +15
Nearly all star clusters younger than ~600 Myr exhibit extended main sequence turn offs and split main sequences (MSs) in their color-magnitude diagrams. Works based on both photom…
