摘要：

In this paper we use a recently introduced approximation method to compute analytical approximate polynomial solutions for some well-known classes of Lane-Emden type equations. The method, called the squared remainder minimization method, is tested on several applications of the Lane-Emden equations including the standard Lane-Emden equation, the white-dwarf equation and the isothermal gas spheres equation. The results of an extensive comparison with previous results emphasizes the accuracy of the method. (C) 2013 Elsevier B.V. All rights reserved.
