摘要：

We study the evolution of a massive primordial hard black hole binary (BHB) in small- and intermediate-size isolated star clusters, modelled as proxies of galactic open clusters (OCs), by means of direct N-body simulations. Some of our models show a significant hardening of the BHB in a relatively short time. Some of them merge within the cluster. The perturbation of stars around BHB systems is key to induce their coalescence. Under our assumptions, we estimate a BHB merger rate of R-mrg similar to 2 yr(-1) Gpc(-3). In some cases the BHB triggers tidal disruption events which, however, are not linked to the GW emission.
