Blue Straggler Bimodality: a Brownian Motion Model
Mario Pasquato, Paolo Miocchi, Suk-Jin Yoon
The shape of the radial distribution of Blue Straggler Stars (BSS), when normalized to a reference population of Horizontal Branch (HB) stars, has been found to be a powerful indic…
Proper motions and structural parameters of the Galactic globular cluster M71
M. Cadelano, E. Dalessandro, F. R. Ferraro +4
By exploiting two ACS/HST datasets separated by a temporal baseline of ~7 years, we have determined the relative stellar proper motions (providing membership) and the absolute prop…
Investigating mass segregation process in globular clusters with Blue Straggler Stars: the impact of dark remnants
Emiliano Alessandrini, Barbara Lanzoni, Francesco Rosario Ferraro +2
We present the results of a set of N-body simulations aimed at exploring how the process of mass segregation (as traced by the spatial distribution of blue straggler stars, BSSs) i…
Ultra-deep GEMINI near-infrared observations of the bulge globular cluster NGC 6624
S. Saracino, E. Dalessandro, F. R. Ferraro +8
We used ultra-deep and images secured with the near-infrared GSAOI camera assisted by the multi-conjugate adaptive optics system GeMS at the GEMINI South Telescope in Chi…
Globular clusters hosting intermediate-mass black-holes: no mass-segregation based candidates
Mario Pasquato, Paolo Miocchi, Bong Won Sohn +1
Recently, both stellar mass-segregation and binary-fractions were uniformly measured on relatively large samples of Galactic Globular Clusters (GCs). Simulations show that both siz…
No evidence of mass segregation in the low mass Galactic globular cluster NGC 6101
E. Dalessandro, F. R. Ferraro, D. Massari +3
We used a combination of Hubble Space Telescope and ground based data to probe the dynamical state of the low mass Galactic globular cluster NGC 6101. We have re-derived the struct…
