Effects of Poynting-Robertson (P-R) drag, radiation, and oblateness on motion around the L4,5 equilibrium points in the CR3BP

Abstract The research paper under consideration investigates the motion in the vicinity of triangular equilibrium points of the circular restricted three-body problem of a passively gravitating dust particle in the gravitational field for the binaries system (Kruger 60 and Achird). The two bodies of the binary are both oblate radiating stars possessing P-R drag. The position of triangular equilibrium points of the particle is seen to be affected by oblateness, radiation and P-R drag. In our numerical exploration of the binary system Kruger 60 and Achird, we computed the radiation factors qi (i= 1,2) and the velocity of light cd which is a component of the P-R drag. The points are unstable due to the presence of a positive real part of the complex roots.
