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…
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…
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. 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…
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…
