If an isolated black hole is massive enough and if it accretes matter at a fast enough rate, the outer parts of the accretion disk will become self-gravitating and may become unstable, disintegrating into fragments which could form separate stars. The fragmentation would produce around the black hole a ring of gas and stars which would survive even after accretion onto the hole has ceased. The stars in the ring would travel in near-Keplerian orbits, with little velocity dispersion. This torus could have a mass several percent of that of the black hole inside.
