In this paper, by means of N-body simulations, we study the evolution of binary stars in multiple-population clusters and explore the implications of the initial differences in the spatial distribution of different stellar populations for the evolution and survival of their binary stars. Our simulations show that initial differences between the spatial distribution of first-generation (FG) and second-generation (SG) stars can leave a fingerprint in the ","authors_text":"Annibale D'Ercole, Antonio Sollima, Enrico Vesperini, Franca D'Antona, Jongsuk Hong, Stephen L.W.
