Evolution of the kinematic properties of rotating multiple-population globular clusters
Ethan B. White, Enrico Vesperini, Emanuele Dalessandro +1
Globular clusters (GCs) host multiple stellar populations differing in their chemical and dynamical properties. A number of models for the formation of multiple populations predict…
JWST imaging of omega Centauri: II. Evidence for a split white dwarf cooling sequence in the near-infrared
M. Scalco, M. Salaris, L. R. Bedin +11
We present a detailed analysis of the white dwarf cooling sequence (WD CS) in omega Centauri based on combined Hubble Space Telescope (HST) and JWST observations. Our analysis conf…
JWST imaging of omega Centauri -- I. Luminosity and mass functions of its main sequence populations
M. Scalco, R. Gerasimov, L. R. Bedin +10
This paper presents the first study of the most massive globular cluster (GC) in the Milky Way, omega Centauri, employing recently acquired JWST deep images. By combining these dat…
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…
A binary-related origin mediated by environmental conditions for blue straggler stars
Francesco R. Ferraro, Barbara Lanzoni, Enrico Vesperini +7
Blue stragglers are anomalously massive core hydrogen-burning stars that, according to the theory of single star evolution, should not exist. They are suspected to form in mass-enh…
Structural parameters, chronological age and dynamical age of the LMC globular cluster NGC 1754
Camilla Giusti, Mario Cadelano, Francesco R. Ferraro +4
In the context of a new systematic study of the properties of the most compact and massive star clusters in the Large Magellanic Cloud (LMC), here we present the determination of t…
SIEGE IV: compact star clusters in cosmological simulations with high star formation efficiency and sub-parsec resolution
R. Pascale, F. Calura, E. Vesperini +10
The formation of compact high-redshift star-forming clumps, the physical processes driving their evolution and their potential connection to present-day Globular Clusters are key o…
The internal kinematics of NGC 2808 and its multiple populations
M. Griggio, A. Bellini, F. I. Aros +10
We use new HST observations coupled with archival data spanning a total temporal baseline of 17 years to study the internal kinematics of the multiple populations in the globular c…
Phase-space mixing of multiple stellar populations in globular clusters
Francisco I. Aros, Enrico Vesperini, Emanuele Dalessandro
Context: Globular clusters (GCs) host multiple populations characterised by abundance variations in a number of light elements. In many cases, these populations also show spatial a…
Tracing the W3/W4/W5 and Perseus complex dynamical evolution with star clusters
A. Della Croce, E. Dalessandro, E. Vesperini +4
The Perseus complex offers an ideal testbed to study cluster formation and early evolution as it hosts two major hierarchical structures (namely LISCA I and LISCA II) and the W3/W4…
A JWST project on 47 Tucanae. Binaries among multiple populations
A. P. Milone, A. F. Marino, M. Bernizzoni +25
Almost all globular clusters (GCs) contain multiple populations consisting of stars with varying helium and light-element abundances. These populations include first-population sta…
Exploring the formation environment of multiple stellar populations in Globular Clusters through binary systems
E. Bortolan, J. Bruce, A. P. Milone +9
Globular Clusters (GCs) are known to host distinct stellar populations, characterized by different chemical compositions. Despite extensive research, the origin of these population…
A JWST project on 47 Tucanae: kinematics, energy equipartition and anisotropy of multiple populations
T. Ziliotto, A. P. Milone, G. Cordoni +17
Recent work with JWST has demonstrated its capability to identify and chemically characterize multiple populations in globular clusters down to the H-burning limit. In this study,…
JWST photometry and astrometry of 47 Tucanae. Discontinuity in the stellar sequence at the star/brown dwarf transition
M. Scalco, R. Gerasimov, L. R. Bedin +10
Using JWST Near Infrared Camera (NIRCam) images of the globular cluster 47 Tucanae (or NGC 104), taken at two epochs just 7 months apart, we derived proper-motion membership down t…
