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…
Connecting photometric and spectroscopic granulation signals with CHEOPS and ESPRESSO
S. Sulis, M. Lendl, H. Cegla +83
Stellar granulation generates fluctuations in photometric and spectroscopic data whose properties depend on the stellar type, composition, and evolutionary state. In this study, we…
Photometry and astrometry with JWST -- I. NIRCam Point Spread Functions and the first JWST colour-magnitude diagrams of a globular cluster
D. Nardiello, L. R. Bedin, A. Burgasser +4
As the James Webb Space Telescope (JWST) has become fully operational, early-release data are now available to begin building the tools and calibrations for precision point-source…
Astro-photometric study of M37 with Gaia and wide-field ugi-imaging
M. Griggio, L. R. Bedin, R. Raddi +15
We present an astrometric and photometric wide-field study of the Galactic open star cluster M37 (NGC 2099). The studied field was observed with ground-based images covering a regi…
The GAPS Programme with HARPS-N at TNG. XXXV. Fundamental properties of transiting exoplanet host stars
K. Biazzo, V. D'Orazi, S. Desidera +38
Exoplanetary properties depend on stellar properties: to know the planet with accuracy and precision it is necessary to know the star as accurately and precisely as possible. Our i…
The Interferometric Binary Epsilon Cancri in Praesepe: Precise Masses and Age
Leslie M. Morales, Eric L. Sandquist, Gail H. Schaefer +16
We observe the brightest member of the Praesepe cluster, Epsilon Cancri, to precisely measure the characteristics of the stars in this binary system, en route to a new measurement…
