Triangular equilibrium points in photogravitational restricted three body problem with poynting -Robertson drag

We have found the equations of Motion of photogravitational restricted three body problem with poynting -Robertson Drag. We consider both primaries as radiating. We have found the position of triangular equilibrium points. The position of equilibrium points is affacted by radiation pressure and P-R Drag. All photogravitational and classical results of RTBP may be verified from this result.
