N-body simulations with BSSs: defining mass segregation indicators.
Abstract
Blue Straggler stars (BSSs) are proven tools to measure the level of mass segregation and the dynamical age of globular clusters (GCs). In order to study the segregation process of BSSs as a function of time, we are performing N-body simulations of GCs also including a population of massive stellar remnants. In this context we have defined a new indicator of mass segregation based on the comparison between the cumulative BSS radial distribution and that of a reference population. Preliminary results are shown.
