Ω(r,θ)/Ωe =  constant curves inside the stellar envelope of a model star with a global shape generated with an equatorial rotational parameter ηo = 0.8 and a surface differential rotation represented by a Maunder relation with parameter α =  +0.3. All curves were generated with parameters ΥJ,Ω,ϵΩ = 0.3 and 1.6. The iso-rotation curves in a1) and a2) correspond to S = S(j2); those in b1) and b2) are for S = S2); the curves in c1) and c2) obey the condition S = S(ϖ2Ω2). The solutions are supposed to be valid in the convective zones above the shaded domain.
