Effect of Perturbations in Coriolis and Centrifugal Forces in the Motion of Infinitesimal Mass Around L₄ in the Photogravitational Restricted Three Body Problem

A Lagrangian formula for the three dimensional motion of a satellite in the vicity of the non collinear points of the photogravitational circular restricted three body problem is considered. It is shown that the motion around L4 gets influenced by radiation pressure and perturbation in centrifugal force. It is observed that the motion around L4 does not get affected by the perturbation in coriolis force.
