Globular Clusters in the Time of the JWST. I. Survey Design and First Results on Multiple Populations and Beyond
A. P. Milone, A. F. Marino, G. Cordoni +25
Globular clusters (GCs) host multiple stellar populations with distinct chemical compositions, but their properties among very low-mass stars remain poorly constrained. The James W…
The pollution from massive AGB stars favoured by strong hot bottom burning
Paolo Ventura, Francesca D'Antona
Stars of intermediate mass (~4-8Msun) evolve to the stage of white dwarfs through the asymptotic giant branch (AGB) stage: stationary hydrogen shell burning and helium thermal puls…
A deep HST view of the open cluster NGC2158: binaries, mass functions, and M-dwarf discontinuity
A. V. Marchuk, F. Muratore, A. P. Milone +13
A significant fraction of stars in both the Galactic field and stellar clusters are members of binary systems. Understanding their properties is therefore essential for a comprehen…
An HST/WFC3 view of stellar populations on the Horizontal Branch of NGC 2419
M. Di Criscienzo, M. Tailo, A. P. Milone +4
We use images acquired with the Hubble Space Telescope Wide Field Camera 3 and new models to probe the Horizontal Branch (HB) population of the We use images acquired with the Hubb…
Adiabatic solar-like oscillations in red giant stars
J. Montalban, A. Miglio, A. Noels +3
Since the detection of non-radial solar-like oscillation modes in red giants with the CoRoT satellite, the interest in the asteroseismic properties of red giants and the link with…
The oxygen vs. sodium (anti)correlation(s) in omega Cen
F. D'Antona, A. D'Ercole, A. F. Marino +3
Recent exam of large samples of omega Cen giants shows that it shares with mono-metallic globular clusters the presence of the sodium versus oxygen anticorrelation, within each sub…
Abundances for a large sample of red giants in NGC 1851: hints for a merger of two clusters?
E. Carretta, R. G. Gratton, S. Lucatello +8
We present the abundance analysis of a sample of more than 120 red giants in the globular cluster (GC) NGC 1851, based on FLAMES spectra. We find a small but detectable metallicity…
Rb-rich Asymptotic Giant Branch stars in the Magellanic Clouds
D. A. Garcia-Hernandez, A. Manchado, D. L. Lambert +6
We present high-resolution (R~60,000) optical spectra of a carefully selected sample of heavily obscured and presumably massive O-rich Asymptotic Giant Branch (AGB) stars in the Ma…
Lithium during the AGB evolution in young open clusters of the Large Magellanic cloud
C. Maceroni, V. testa, B. Plez +2
We present the results of mid-resolution spectroscopy in the LiI 6708 AA spectral region of Asymptotic Giant Branch (AGB) stars belonging to young open clusters of the Large Magell…
A Young Very Low-Mass Object surrounded by warm dust
L. Testi, A. Natta, E. Oliva +5
We present a complete low-resolution (R~100) near-infrared spectrum of the substellar object GY11, member of the rho-Ophiuchi young association. The object is remarkable because of…
