The evolution of the binary population in globular clusters: a full analytical computation
A. Sollima
I present a simplified analytical model that simulates the evolution of the binary population in a dynamically evolving globular cluster. A number of simulations have been run span…
A Correlation between Blue Straggler and Binary Fractions in the core of Galactic Globular Clusters
A. Sollima, B. Lanzoni, G. Beccari +2
Context. Blue Stragglers Stars (BSSs) are thought to form in globular clusters by two main formation channels: i) mergers induced by stellar collisions and ii) coalescence or mass-…
The infrared JHK light curves of RR Lyr
A. Sollima, C. Cacciari, A. A. Arkharov +4
We present infrared JHK time series photometry of the variable star RR Lyr, that allow us to construct the first complete and accurate infrared light curves for this star. The deri…
The surprising external upturn of the Blue Straggler radial distribution in M55
B. Lanzoni, E. Dalessandro, S. Perina +4
By combining high-resolution HST and wide-field ground based observations, in ultraviolet and optical bands, we study the Blue Straggler Star (BSS) population of the low density ga…
Modeling the chemical evolution of Omega Centauri using three-dimensional hydrodynamical simulations
A. Marcolini, A. Sollima, A. D'Ercole +2
We present a hydrodynamical and chemical model for the globular cluster Omega Cen, under the assumption that it is the remnant of an ancient dwarf spheroidal galaxy (dSph), the bul…
The Mass Function of omega Centauri down to 0.15 M_s
A. Sollima, F. R. Ferraro, M. Bellazzini
By means of deep FORS1@VLT and ACS@HST observations of a wide area in the stellar system omega Cen we measured the luminosity function of main sequence stars down to R=22.6 and I_{…
