Multiple populations along the asymptotic giant branch: a Gaia+APOGEE study of 22 Galactic globular clusters
Emanuele Dondoglio, A. P. Milone, A. F. Marino +9
We present an investigation of multiple stellar populations along the asymptotic giant branch (AGB) in 22 globular clusters (GCs), exploiting APOGEE spectroscopy combined with AGB…
Hubble Space Telescope survey of Magellanic Cloud star clusters. Binaries, mass functions, blue stragglers, and structural parameters
F. Muratore, M. V. Legnardi, A. P. Milone +7
Binary stars are key tracers of the dynamical evolution of star clusters and provide important constraints on stellar populations and mass functions. The Magellanic Clouds host clu…
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…
Exploring the ultra-faint dwarf Bootes I using JWST and HST: Metallicity distribution and binaries
F. Muratore, M. V. Legnardi, A. P. Milone +8
Ultra-faint dwarf galaxies (UFDs) are among the oldest and most metal-poor stellar systems in the Universe. Their metallicity distribution encodes the fossil record of the earliest…
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…
A joint JWST and HST view of Omega Centauri: Multiple stellar populations and their kinematics
T. Ziliotto, A. P. Milone, G. Cordoni +5
We combine F115W and F277W images collected with the Near Infrared Camera of the James Webb Space Telescope (JWST) with multi-band, multi-epoch Hubble Space Telescope (HST) observa…
