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…
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…
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…
Probing the role of dynamical friction in shaping the BSS radial distribution. I - Semi-analytical models and preliminary N-body simulations
P. Miocchi, M. Pasquato, B. Lanzoni +5
We present semi-analytical models and simplified -body simulations with and particles aimed at probing the role of dynamical friction (DF) in determining the radia…
Star count density profiles and structural parameters of 26 Galactic globular clusters
P. Miocchi, B. Lanzoni, F. R. Ferraro +6
We used a proper combination of high-resolution HST observations and wide-field ground based data to derive the radial star density profile of 26 Galactic globular clusters from re…
