Radial profile of the torques exerted by the wind (ℳ_surf, yellow curve) and the sum of the radial torques and planet torques (ℛ_R, ℳ_r and 𝒫, blue curve), averaged over the episode ℰ₂ in the run Mj-β₃. The black curve displays the sum of all torques enumerated in Eq. (22). We removed the contribution close to the planet and its CPD in the evaluation of the planet and radial torques. We add three labels to identify different angular momentum redistribution phenomena that we believe are essential in apprehending the gap asymmetries. (a) Angular momentum deposition by the outer planet wake at the gap’s outer edge. (b) Angular momentum evacuation in the wind. (c) Inefficient angular momentum extraction by the inner planet wake at the gap’s inner edge, and small value of the wind torque.
