  We model self-gravitating disks in Keplerian motion around the primary black
hole, in the binary black hole system OJ 287 with a torus, employing a
consistently general-relativistic approach. They satisfy geometric and/or mass
density requirements found by Sillanpaa, Valtonen, Lehto and their coworkers.
It is plausible that essential observational features of OJ 287 can be obtained
via the general-relativistic description of the Bondi-Hoyle-Lyttleton transits
through these tori, within the framework of radiation hydrodynamics.
