Curves of internal constant angular velocity Ω(r,θ) = const. in the stellar envelope (blue lines). a) Curves corresponding to the condition S = S(j2); b) curves obtained with S = S(Ω2); and c) curves calculated for S = S(ϖ2Ω2). The solutions are valid in the convective envelope, i.e., above the shaded central region (S = specific entropy; j = specific angular momentum; and ϖ = distance to the rotation axis). Ordinates coincide with the rotation axis; abscissas are in the equatorial plane.
