Euclid: The convective-transition gap of 47 Tuc
M. Libralato, M. Griggio, R. Gerasimov +140
We report the first detection of the `convective-transition gap' (also known as `M-dwarf gap') in the globular cluster 47 Tuc (NGC 104) thanks to Euclid data. This feature, linked…
Euclid Quick Data Release (Q2) -- The Euclid Galactic Bulge Survey
J. -P. Beaulieu, E. Bachelet, M. Gilles +173
The Euclid Quick Data Release Q2 provides an unprecedented deep, wide-field, high-angular-resolution view of the inner Galactic bulge through the Euclid Galactic Bulge Survey (EGBS…
Euclid: Early Release Observations -- Internal kinematics and the convective-transition gap of NGC 6397
M. Griggio, M. Libralato, R. Gerasimov +130
We present a 'multiple-pass' data-reduction tool designed for Euclid, based on software developed for the Hubble Space Telescope (HST), which improves the astrometric and photometr…
The Y Dwarf Population with HST: unlocking the secrets of our coolest neighbours -- III. Near-Infrared Photometry
Clémence Fontanive, Luigi R. Bedin, Mark W. Phillips +4
Y dwarfs represent the coldest class of brown dwarfs, with effective temperatures below 500K, and provide unique analogues to cold giant exoplanets. We present a large compilation…
Astrometric Reconnaissance of Exoplanetary Systems (ARES). I. Methodology validation with HST point-source images of Proxima Centauri
M. Libralato, L. Bedin, A. Burgasser
We present the first results of the Astrometric Reconnaissance of Exoplanetary Systems (ARES) project, aimed at validating and characterizing candidate exoplanets around the neares…
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…
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…
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 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…
The GAPS Programme at TNG. LXV. Precise density measurement of TOI-1430 b, a young planet with an evaporating atmosphere
D. Nardiello, J. M. Akana Murphy, R. Spinelli +34
Small-sized exoplanets in tight orbits around young stars (10-1000 Myr) give us the opportunity to investigate the mechanisms that led to their formation, the evolution of their ph…
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…
The Hubble Space Telescope UV Legacy Survey of Galactic Globular Clusters - XV. The dynamical clock: reading cluster dynamical evolution from the segregation level of blue straggler stars
F. R. Ferraro, B. Lanzoni, S. Raso +17
The parameter A+, defined as the area enclosed between the cumulative radial distribution of blue straggler stars (BSSs) and that of a reference population, is a powerful indicator…
