Effect of perturbations and oblateness of more massive primary on the location of triangular points in the restricted three body problem

The effect of perturbations in the coriolis and the centrifugal forces together with the oblateness of more massive primary on the location of triangular points in the restricted three body problem has been studied. It is found that the points L4 and L5 form triangles with the primaries. The positions of these points are not effected by the change in the coriolis force. They are affected by the change in the centrifugal force and oblateness of the more massive primary.
