Dating N loud AGNs at high redshift: GS3073 as a snapshot of wCen like evolution of a nuclear star cluster
F. D'Antona, P. Ventura, A. F. Marino +8
In this paper we address two major questions raised by recent James Webb Space Telescope observations of the young Universe, namely: 1) what are the seed initial masses, and how ra…
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…
HST observations of the globular cluster NGC 6402 (M14) and its peculiar multiple populations
Francesca D'Antona, Antonino P. Milone, Christian I. Johnson +6
We present Hubble Space Telescope (HST) photometric results for NGC 6402, a highly reddened very luminous Galactic globular cluster (GC). Recent spectroscopic observations of its r…
Mass loss law for red giant stars in simple population globular clusters
M. Tailo, A. P. Milone, E. P. Lagioia +12
The amount of mass lost by stars during the red-giant branch (RGB) phase is one of the main parameters to understand and correctly model the late stages of stellar evolution. Never…
Mass loss along the red giant branch in 46 Globular Clusters and their multiple populations
M. Tailo, A. P. Milone, E. P. Lagioia +7
The location of Galactic Globular Clusters' (GC) stars on the horizontal branch (HB) should mainly depend on GC metallicity, the "first parameter", but it is actually the result of…
Is helium the key parameter in the extended color spread of the first generation stars in M3?
M. Tailo, F. D'Antona, V. Caloi +4
The study of the "chromosome maps" of Galactic Globular Clusters has shown that the stars identified as `first generation' often define an extended sequence in the $m_{F275W}-m_{F8…
