Perturbation solutions are obtained for the Lane-Emden equation of the second kind which describe Bonnor-Ebert gas spheres In particular, we employ the field-theoretic perturbative procedure due to Bender et at to obtain analytical solutions to the nonlinear initial value problem We find that the method allows one to construct perturbation solutions which converge rapidly to the true solutions in many cases, as it allows one to more accurately represent the influence of nonlinear terms in the linearized equations The rapid convergence of the method results in qualitatively accurate solutions in relatively few iterations.
