Kumar, Sunil; Lal, A. K.; Sharma, H. G.; Singh, V. P. Equilibrium structures of differentially rotating polytropic stars. (English) Zbl 1355.85002 Aligarh Bull. Math. 29, No. 2, 135-147 (2010). Using a fourth-order Runge-Kutta method, the authors numerically solved the problem mentioned in the title of this paper. They applied four different values of the polytropic index.
