| Abstract: | In this paper we develop and implement a  complex-plane iterative technique for computing rotating visco-polytropic models. The viscosity of the models is determined in view of the relaxation condition that differential rotation depends only on the distance from the rotation axis. To this purpose we develop and implement a viscosity-evaluated-upwards technique which fits viscosity, within a few percent, with the required condition. We compute various models, and we study in detail some of them that satisfy, within a few percent, the condition above, and also the boundary condition of a vanishing surface stress vector. |
