Photometry and astrometry with JWST -- II. NIRCam distortion correction
M. Griggio, D. Nardiello, L. R. Bedin
In preparation to make the most of our own planned James Webb Space Telescope investigations, we take advantage of publicly available calibration and early-science observations to…
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…
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…
Signature of a chemical spread in the open cluster M37
M. Griggio, M. Salaris, S. Cassisi +2
Recent Gaia photometry of the open cluster M37 have disclosed the existence of an extended main-sequence turn off -- like in Magellanic clusters younger than about 2 Gyr -- and a m…
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…
Astrometric star-cluster membership probability: application to the case of M 37 with Gaia EDR3
M. Griggio, L. R. Bedin
In this work, starting from the well-accepted relations in literature, we introduce a new formalism to compute the astrometric membership probabilities for sources in star clusters…
