A new class of fossil fragments from the hierarchical assembly of the Galactic bulge
F. R. Ferraro, C. Pallanca, B. Lanzoni +12
The formation and evolutionary processes of galaxy bulges are still unclear, and the presence of young stars in the bulge of the Milky Way is largely debated. We recently demonstra…
PSR J1641+3627F: a low-mass He white dwarf orbiting a possible high-mass neutron star in the globular cluster M13
Mario Cadelano, Jianxing Chen, Cristina Pallanca +5
We report on the discovery of the companion star to the millisecond pulsar J1631+3627F in the globular cluster M13. By means of a combination of optical and near-UV high-resolution…
The RGB tip of galactic globular clusters and the revision of the bound of the axion-electron coupling
O. Straniero, C. Pallanca, E. Dalessandro +5
By combining Hubble Space Telescope (HST) and ground based optical and near-infrared photometric samples, we derive the RGB tip absolute magnitude of 22 galactic globular clusters…
A kinematic view of NGC 1261: structural parameters, internal dispersion, absolute proper motion and Blue Straggler Stars
S. Raso, M. Libralato, A. Bellini +8
We constructed a Hubble Space Telescope (HST) astro-photometric catalog of the central region of the Galactic globular cluster NGC 1261. This catalog, complemented with Gaia DR2 da…
The proper motion of sub-populations in Omega Centauri
N. Sanna, E. Pancino, A. Zocchi +2
The galactic globular cluster Omega Centauri is the most massive of its kind, with a complex mix of multiple stellar populations and several kinematic and dynamical peculiarities.…
The "dynamical clock": dating the internal dynamical evolution of star clusters with Blue Straggler Stars
F. R. Ferraro, B. Lanzoni, E. Dalessandro
We discuss the observational properties of a special class of objects (the so-called "Blue Straggler Stars", BSSs) in the framework of using this stellar population as probe of the…
