Summary

By means of high-resolution (HST) and wide-field (GALEX and ground-based) observations in the UV and optical bands, we have derived the radial distribution of the Blue Stragglers Star population in a number of galactic globular clusters. Monte-Carlo dynamical simulations have been used to interpret the radial distributions and to infer clues on the formation mechanisms of these puzzling stars.
