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…
Exploring the Chemistry and Mass Function of the Globular Cluster 47 Tucanae with New Theoretical Color-Magnitude Diagrams
Roman Gerasimov, Adam J. Burgasser, Ilaria Caiazzo +4
Despite their shared origin, members of globular clusters display star-to-star variations in composition. The observed pattern of element abundances is unique to these stellar envi…
An Extremely Massive White Dwarf Escaped From the Hyades Star Cluster
David R. Miller, Ilaria Caiazzo, Jeremy Heyl +5
We searched the Gaia DR3 database for ultramassive white dwarfs with kinematics consistent with having escaped the nearby Hyades open cluster, identifying three such candidates. Tw…
A rotating white dwarf shows different compositions on its opposite faces
Ilaria Caiazzo, Kevin B. Burdge, Pier-Emmanuel Tremblay +35
White dwarfs, the extremely dense remnants left behind by most stars after their death, are characterised by a mass comparable to that of the Sun compressed into the size of an Ear…
Carbon stars as standard candles -- III. Un-binned maximum likelihood fitting and comparison with TRGB estimations
Javiera Parada, Jeremy Heyl, Harvey Richer +2
In the second paper of this series, we developed a new distance determination method using the median magnitude of carbon-rich asymptotic giant branch stars (CS) as standard ca…
The HST large programme on NGC 6752 -- IV. The White Dwarf Sequence
L. R. Bedin, M. Salaris, J. Anderson +13
We present our final study of the white dwarf cooling sequence (WD CS) in the globular cluster NGC 6752. The investigation is the main goal of a dedicated Hubble Space Telescope la…
