First Order Normalization in the Generalized Photogravitational Restricted Three Body Problem with Poynting-Robertson Drag

Abstract

In this paper we have studied non-linear stability of triangular equilibrium points. We have performed first order normalization in the generalized photogravitational restricted three body problem with Poynting-Robertson drag. In this problem we have taken bigger primary as source of radiation and smaller primary is an oblate spheroid. At first we have expanded the Lagrangian function in power series of x and y, where (x, y) are the coordinates of the triangular equilibrium points. Then the relation between the roots of the characteristic equation for the linearised system is obtained. Key Words:First order normalization / Generalised Photogravitational/ RTBP.
