In a recent paper we have shown that the evolution of a misaligned discaround a spinning black hole can result in tearing the disc into many distinctplanes. Tearing discs with random orientations produce direct dynamicalaccretion on to the hole in approximately 70% of all cases. Here we examine theevolution of a misaligned disc around a binary system. We show that these discsare susceptible to tearing for almost all inclinations. We also show thattearing of the disc can result in a significant acceleration of the discevolution and subsequent accretion on to the binary - by factors up to 10,000times that of a coplanar prograde disc with otherwise identical parameters.This provides a promising mechanism for driving mergers of supermassive blackhole (SMBH) binaries on timescales much shorter than a Hubble time. Disctearing also suggests new observational signatures of accreting SMBH binaries,and other systems such as protostellar binaries.
