Trajectories of $L_4$ and Lyapunov Characteristic Exponents in the Generalized Photogravitational Chermnykh-Like Problem

Abstract

The dynamical behaviour of near by trajectories is being estimated by Lyapunov Characteristic Exponents(LCEs) in the Generalized Photogravitational Chermnykh-Like problem. It is found that the trajectories of the Lagrangian point $L_4$ move along the epicycloid path, and spirally depart from the vicinity of the point. The LCEs remain positive for all the cases and depend on the initial deviation vector as well as renormalization time step. It is noticed that the trajectories are chaotic in nature and the $L_4$ is asymptotically stable. The effects of radiation pressure, oblateness and mass of the belt are also examined in the present model.
