  The modified Lane-Emden equation for stellar hydrostatic equilibrium in
f(R)-gravity is numerically solved by using an iterative procedure. Such an
integro-differential equation can be obtained in the weak field limit
approximation of f(R)-gravity by considering a suitable polytropic equation of
state in the modified Poisson equation. The approach allows, in principle, to
deal with still unexplored self-graviting systems that could account for exotic
stellar structures that escape standard stellar theory.
