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 not so simple stellar system Omega Cen. II. Evidence in support of a merging scenario
Annalisa Calamida, Alice Zocchi, Giuseppe Bono +7
We present multi-band photometry covering 5° 5°across Cen collected with the Dark Energy Camera, combined to Hubble Space Telescope and Wide Field Imager data fo…
Homogeneous photometry VII. Globular clusters in the Gaia era
P. B. Stetson, E. Pancino, A. Zocchi +2
We present wide-field, ground-based Johnson-Cousins UBVRI photometry for 48 Galactic globular clusters based on almost 90000 public and proprietary images. The photometry is calibr…
The Peculiar Radial Distribution of Multiple Populations in the massive globular cluster M80
E. Dalessandro, M. Cadelano, E. Vesperini +7
We present a detailed analysis of the radial distribution of light-element multiple populations (LE-MPs) in the massive and dense globular cluster M80 based on the combination of U…
The properties of energetically unbound stars in stellar clusters
Ian Claydon, Mark Gieles, Alice Zocchi
Several Milky Way star clusters show a roughly flat velocity dispersion profile at large radii, which is not expected from models with a tidal cut-off energy. Possible explanations…
Biases in the determination of dynamical parameters of star clusters: today and in the Gaia era
A. Sollima, H. Baumgardt, A. Zocchi +4
The structural and dynamical properties of star clusters are generally derived by means of the comparison between steady-state analytic models and the available observables. With t…
