Query: Investigating the Blue Straggler Stars radial distribution in globular
  clusters with Monte Carlo simulations   We investigate the evolution of the radial distribution of Blue Straggler
Stars through a set of Monte Carlo simulations of star clusters under a variety
of initial conditions. We used a novel technique based on the "artificial
oversampling" of the distribution function of the Blue Stragglers and control
population to tear down the effect of statistical fluctuations affecting the
determination of the relative distribution of these stellar populations. We
find that a bimodal distribution, qualitatively similar but much less
pronounced than those observed in many globular clusters, can naturally emerge
as a result of the progressive migration of Blue Stragglers in the energy
domain. The behaviour of the parameter A+, proposed as a "dynamical age"
indicator, has been also investigated. This parameter shows a relatively
homogeneous and well defined trend with the fraction of the elapsed
core-collapse timescale up to the core collapse phase, while after this stage
its evolution depends on initial conditions.
