Euclid: High-precision imaging astrometry and photometry from Early Release Observations. I. Internal kinematics of NGC 6397 by combining Euclid and Gaia data
M. Libralato, L. R. Bedin, M. Griggio +175
The instruments at the focus of the Euclid space observatory offer superb, diffraction-limited imaging over an unprecedented (from space) wide field of view of 0.57 deg. This e…
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…
When Do Stars Go BOOM?
Harvey B. Richer, Roger E. Cohen, Matteo Correnti +10
The maximum mass of a star that can produce a white dwarf (WD) is an important astrophysical quantity. One of the best approaches to establishing this limit is to search for WDs in…
The Minimum Mass of Rotating Main Sequence Stars and its Impact on the Nature of Extended Main Sequence Turnoffs in Intermediate-Age Star Clusters in the Magellanic Clouds
Paul Goudfrooij, Leo Girardi, Andrea Bellini +3
Extended main sequence turn-offs (eMSTOs) are a common feature in color-magnitude diagrams (CMDs) of young and intermediate-age star clusters in the Magellanic Clouds. The nature o…
The Age of the Old Metal-Poor Globular Cluster NGC6397 Using WFC3/IR Photometry
Matteo Correnti, Mario Gennaro, Jason S. Kalirai +2
Globular Clusters (GCs) in the Milky Way represent the ideal laboratory to establish the age of the oldest stellar populations and to measure the color-magnitude relation of stars.…
On the use of the main sequence knee (saddle) to measure globular cluster ages
S. Saracino, E. Dalessandro, F. R. Ferraro +11
In this paper we review the operational definition of the so-called main sequence knee (MS-knee), a feature in the color-magnitude diagram (CMD) occurring at the low-mass end of th…
