Average surface density (top panel) and cumulative gravitational torque (bottom panel; the gravitational torque density integrated from ﹩r^{\prime} =0﹩ to ﹩r^{\prime} =r﹩, normalized by the accretion rate onto the binary) profiles for binaries accreting from ﹩{ \mathcal M }=10﹩ disks. Similar changes in both the surface density and cumulative torque profiles occur for both viscosities, the disk moving inward and the overall torque becoming negative. Each profile was averaged over the final 500 binary orbits of each simulation.
