Results for supersynchronous rotation in a circular orbit for polytropic indices n = 1.5 (left, Case 3) and n = 3 (right, Case 31). Top: angular velocity (⟨ω″⟩+δω″) at the equator in the ten layers used for this calculation. Dashes correspond to layers closest to the surface, r/R = 6.65 and 6.22. The abscissa is azimuth angle measured in degrees with φ′ = 0 corresponding to the sub-binary longitude. Bottom: meridional ω″ profiles at the equator for a selection of meridians φ′ as indicated by the labels. The abscissa is the radius at the midpoint of each layer. The behavior for r/R < 5 is shown on an amplified scale in the inset.
