Properties of a steady disk around an SMBH binary with mass M _c = 10 ⁵  M _☉ described by a solution (15) with F _{J, 0} = 5 × 10 ⁴⁶ erg and a mass accretion rate at infinity (a radiative efficiency of 0.1 is assumed). Solid (black) curves describe the run of (a) aspect ratio h/ r, (b) temperature T, (c) surface density Σ, and (d) angular momentum flux F _J with r for a disk with b = 0 in a radiation pressure-dominated part of the disk. Dashed (blue) curves describe the same but for a standard constant disk with the same mass accretion rate . Dotted extensions of these curves at small r correspond to b = 1 in the radiation pressure-dominated part of the disk. Open dots on each curve correspond to the transition between the radiation and gas pressure-dominated regimes, while filled dots describe the transition between the electron scattering and free–free opacity.
