Periodic orbits around L4 in the photogravitational restricted problem with oblate primaries

In this paper, we have studied periodic orbits generated by L4 in the restricted three body problem when both the primaries are radiating oblate bodies. We have determined periodic orbits for different values of µ, h, σ1, σ2, p1 and p2 (h is energy constant, µ mass ratio of the two primaries, σ1 and σ2 are oblateness factors and p1 and p2 are radiation parameters). These orbits have been determined by giving displacements along the tangent and normal to the mobile coordinates as defined in our papers (Mittal et. al. [3, 4]). We have also studied the effect of oblateness and radiation pressures on periodic orbits by taking some values of µ, σ1, σ2, p1 and p2.
