JWST imaging of the closest globular clusters -- IV. Chemistry, luminosity, and mass functions of the lowest-mass members in the NIRISS parallel fields
M. Libralato, R. Gerasimov, L. Bedin +9
We present observations of the two closest globular clusters, NGC 6121 and NGC 6397, taken with the NIRISS detector of JWST. The combination of our new JWST data with archival Hubb…
The HST Large Programme on Omega Centauri -- VII. The white dwarf cooling sequence
M. Scalco, M. Salaris, L. Bedin +9
We present a study of the white dwarf (WD) cooling sequence (CS) in the globular cluster (GC) Omega Centauri, the primary goal of a dedicated Hubble Space Telescope (HST) programme…
The HST Large Programme on omega Centauri -- VI. The radial gradient of the stellar populations
Michele Scalco, Luigi Bedin, Enrico Vesperini
In this paper we present the analysis of Hubble Space Telescope (HST) observations of the globular cluster Omega Centauri. Our analysis combines data obtained in this work with pre…
JWST Imaging of the Closest Globular Clusters -- I. Possible Infrared Excess Among White Dwarfs in NGC 6397
L. R. Bedin, D. Nardiello, M. Salaris +9
We present James Webb Space Telescope observations of the globular cluster NGC 6397 and use them to extend to infrared wavelengths the characterization of the cluster's entire whit…
JWST Imaging of the Closest Globular Clusters -- III. Multiple Populations along the low-mass Main Sequence stars of NGC 6397
M. Scalco, M. Libralato, R. Gerasimov +9
Thanks to its exceptional near-infrared photometry, JWST can effectively contribute to the discovery, characterization, and understanding of multiple stellar populations in globula…
The Large Programme on NGC6752 -- V. Differences in Luminosity and Mass Functions among Multiple Stellar Populations
M. Scalco, R. Gerasimov, L. R. Bedin +8
We exploit the astro-photometric dataset of the multi-epoch infrared parallel field of a Large Programme aimed at studying the faintest stars of t…
