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…
Detection of a white dwarf orbiting a Carbon-Oxygen depleted blue straggler in 47 Tucanae
Elisabetta Reggiani, Mario Cadelano, Barbara Lanzoni +3
We have employed deep far-UV observations secured with the Solar Blind Channel of the Advanced Camera for Surveys onboard the Hubble Space Telescope to search for hot companions to…
James Webb Space Telescope observations of the white dwarf cooling sequence of 47 Tucanae
M. Salaris, M. Scalco, L. R. Bedin +1
We present a study of the white dwarf (WD) cooling sequence of the globular cluster 47 Tucanae (47 Tuc or NGC 104) using deep infrared observations with the James Webb Space Telesc…
JWST Imaging of the Closest Globular Clusters -- V. The White Dwarfs Cooling Sequence of M4
L. R. Bedin, M. Libralato, M. Salaris +9
We combine infrared (IR) observations collected by the James Webb Space Telescope with optical deep images by the Hubble Space Telescope taken approximately 20 years earlier to com…
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…
