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…
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…
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…
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,…
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…
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…
