Rotation profiles in the envelopes of planets of varying masses. We define the regions in the surroundings of the planet according to the rotational state of the envelope. We note that the region labelled CPD is only appropriately named for masses of m_p ≥ 240 m_⊕. The strict transition into the Keplerian shear of the CSD happens at v_θ∕v_Kepler=−1, as can be seen from the slope turnover in the rotation curves. The vertical black dashed curve denotes r = 0.3r_H, where rotation and density asymmetry values are measured and plotted in Fig. 2.
