Production of EMRIs in supermassive black hole binaries

摘要: We consider the formation of extreme mass-ratio inspirals (EMRIs) sourced from a stellar cusp centred on primary supermassive black hole (SMBH) and perturbed by an inspiraling less massive secondary SMBH. The problem is approached numerically, assuming stars are non-interacting over these short time-scales performing ensemble restricted three-body integrations. From simulations, we see that not only can EMRIs be produced during this process, but dynamics also quite rich. In particular, most through process akin to Kozai–Lidov mechanism, with strong effects due non-Keplerian potential, general relativity non-secular oscillations in angular momentum orbital time-scale binary SMBH system.
