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…
JWST Imaging of the Closest Globular Clusters -- VI. The Lowest-Mass Objects in M 4 and the Galactic Bulge
L. R. Bedin, R. Gerasimov, A. Calamida +8
We present `James Webb Space Telescope' observations of M4 -- the closest globular cluster -- that probe the lower Main Sequence down to the hydrogen-burning limit. The unveiled st…
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…
JWST Imaging of the Closest Globular Clusters -- II. Discovery of Brown Dwarfs in NGC 6397 and Measurement of Age from the Brown Dwarf Cooling Sequence, using SANDee - a New Grid of Model Isochrones across the Hydrogen-Burning Limit
Roman Gerasimov, Luigi R. Bedin, Adam J. Burgasser +4
Globular clusters contain vast repositories of metal-poor stars that represent some of the oldest stellar generations in the Universe. The archaeological footprint of early Galacti…
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…
