Stellar spin in young star clusters: comparison between simulations and observations

Giacomo Cordoni, Sajay Sunny Mathew, Christoph Federrath

The angular momentum evolution of stars is crucial for understanding the formation and evolution of stars and star clusters. Using high-resolution magnetohydrodynamical (MHD) simul…

The impact of rotational mixing in intermediate-age star clusters with extended main-sequence turn-offs and extended red clumps

Lorenzo Martinelli, Andrea Miglio, Gaël Buldgen +6

The extended main-sequence turn-offs (eMSTOs) and extended red clumps (eRCs) observed in intermediate-age star clusters challenge the traditional understanding of clusters as simpl…

Hunting for UVdim stars in Galactic Open clusters. Clues from ultraviolet photometry

G. Cordoni, A. P. Milone, L. Casagrande +7

Split main-sequences (MSs) and extended main-sequence turn-offs (eMSTOs) have been observed in nearly all Magellanic Clouds clusters younger than 2 Gyr. More recently, Hubble Space…

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…

Mass loss along the red giant branch of the intermediate stellar populations in NGC6752 and NGC2808

M. Tailo, A. P. Milone, A. F. Marino +15

The morphology of the Horizontal Branch (HB) in Globular Clusters (GC) is among the early evidences that they contain multiple populations of stars. Indeed, the location of each st…

A JWST project on 47 Tucanae: kinematics, energy equipartition and anisotropy of multiple populations

T. Ziliotto, A. P. Milone, G. Cordoni +17

Recent work with JWST has demonstrated its capability to identify and chemically characterize multiple populations in globular clusters down to the H-burning limit. In this study,…
