Exploring the optical properties of redback pulsars: The case of J1717+4308A in the globular cluster M92
Jianxing Chen, Greta Ettorre, Cristina Pallanca +13
Binary millisecond pulsars (MSPs) in globular clusters (GCs) are key for binary and stellar evolution studies under extreme conditions. The identification of their optical companio…
Binary stars as dynamical tracers in globular clusters .II. Evolution of the radial distribution of the binary star fraction
J. Bruce, E. Vesperini, E. Dalessandro +5
The distinct dynamical environments occupied by multiple stellar populations in globular clusters play a significant role in many aspects of cluster evolution, including the dynami…
Binary Stars as Dynamical Tracers in Globular Clusters .I. First Observations of Bimodal Spatial Distributions
M. Cadelano, E. Dalessandro, J. Bruce +7
We present the first homogeneous study of the radial distribution of the binary fraction across the full extent of six Galactic globular clusters (GCs) spanning a wide range of dyn…
The evolution of high-z proto-star clusters into local globular clusters
A. Della Croce, E. Vesperini, R. Pascale +4
The James Webb Space Telescope (JWST) detected numerous massive and relatively compact stellar clumps around proto-galaxies at high redshift (z>0.5). Their properties suggest that…
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…
A pulsar escaping an ancient open cluster via tidal stripping
Lei Zhang, Xiaoting Fu, Di Li +21
Open clusters are the primary birthplaces of stars in the Milky Way disk, yet their neutron star progeny are rarely found within them, presumably due to supernova-induced kicks tha…
