Time-averaged (in the rotating frame of the binary) surface density profiles with momenta streamlines, for binaries with ﹩{ \mathcal M }=30﹩ disks at q ∈ {0.1, 0.2, 0.5, 1.0}. The equipotential contours of the first, second, and third Lagrange points are illustrated in each case using white curves. In a time-averaged sense, the flow onto the primary from the circumbinary disk transitions from both lagging and leading the primary at high mass ratios to primarily trailing the binary at lower mass ratios, contributing to a less negative overall gravitational torque as q decreases.
