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…
Planetary Nebulae of the Large Magellanic Cloud II: the connection with the progenitors' properties
P. Ventura, S. Tosi, D. A. García-Hernández +6
The study of planetary nebulae (PNe) offers the opportunity of evaluating the efficiency of the dust production mechanism during the very late asymptotic giant branch (AGB) phases.…
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…
Carbon Abundances in Compact Galactic Planetary Nebulae: An Ultraviolet spectroscopic study with the Space Telescope Imaging Spectrograph (STIS)
Letizia Stanghellini, Rafia Bushra, Richard A. Shaw +3
We surveyed a sample of compact Galactic planetary nebulae (PNe) with the Space Telescope Imaging Spectrograph on the Hubble Space Telescope (HST/STIS) to determine their gas-phase…
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…
Gas and dust from extremely metal-poor AGB stars
P. Ventura, F. Dell'Agli, D. Romano +8
We study the evolution of extremely metal-poor AGB stars, with metallicities down to [Fe/H]=-5, to understand the main evolutionary properties, the efficiency of the processes able…
