Tidal disruption events from supermassive black hole binaries

Abstract: We investigate the pre-disruption gravitational dynamics and post-disruption hydrodynamics of the tidal disruption of stars by supermassive black hole (SMBH) binaries. We focus on binaries with relatively low mass primaries (10 6 M ), moderate mass ratios, and separations with reasonably long gravitational wave inspiral times (tens of Myr). First, we generate a large ensemble (between 1 and 10 million) of restricted three-body integrations to quantify the statistical properties of tidal disruptions by circular… Show more

“…We note that the disruptive effect of a SMBH binary on the debris stream of the TDE 30 might also help to explain the fact that the flare observed in F01004-2237 is unusually prolonged.…”

“…In this paper, we discuss a new electromagnetic window into the assembly of BBH mergers in dense stellar clusters (SCs): tidal disruptions (TDs) of stars by BBHs. Previous theoretical work on these events suggests that their lightcurves are interrupted on characteristic timescales related to the orbital period of the disrupting BBHs [e.g., 64,[72][73][74][75]. We propose that populations of such events can be used to probe the orbital period distribution of BBHs inside SCs.…”

“…Since then, a number of other authors have analyzed the tidal disruption of polytropes, with the aim of assessing one or another aspect of the tidal disruption process (e.g. Hayasaki et al 2013;Coughlin & Nixon 2015;Shiokawa et al 2015;Bonnerot et al 2016;Hayasaki et al 2016;Coughlin et al 2016;Mainetti et al 2017;Guillochon & McCourt 2017;Bonnerot et al 2017;Coughlin et al 2017;Wu et al 2018;Golightly et al 2019). However, only relatively few authors have analyzed the disruption of a star with a density profile other than a polytrope.…”
