K2 results for "young" -rich stars in the Galaxy
V. Grisoni, C. Chiappini, A. Miglio +11
The origin of apparently young -rich stars in the Galaxy is still a matter of debate in Galactic archaeology, whether they are genuinely young or might be products of binary evo…
GN-z11: witnessing the formation of second generation stars and an accreting massive black hole in a massive star cluster
F. D'Antona, E. Vesperini, F. Calura +7
We explore the possibility that the N-rich young proto-galaxy GN-z11 recently observed at z=10.6 by the James Webb Space Telescope is the result of the formation of second generati…
The metallicity variations along the chromosome maps: The Globular Cluster 47 Tucanae
A. F. Marino, A. P. Milone, E. Dondoglio +11
The "chromosome maps" (ChMs) of globular clusters (GCs) have revealed that these ancient structures are not homogeneous in metallicity in various ways, and in different natures. Th…
A deep dive into the Type II Globular Cluster NGC 1851
E. Dondoglio, A. P. Milone, A. F. Marino +13
About one-fifth of the Galactic globular clusters (GCs), dubbed Type II GCs, host distinct stellar populations with different heavy elements abundances. NGC 1851 is one of the most…
