Equilateral Triangular Configuration in the Perturbed Circular Restricted Four-Body Problem with Kerr-like Primaries and Variable Mass Test Particle

The aim of this paper is to study the motion behaviour of the variable mass test particle which is moving under the various perturbation effects such as gravitational forces of the primaries, spin about their axes, the transition from the Newtonian to the beyond-Newtonian regime and also due to the Coriolis as well as centrifugal forces in the equilateral triangular configuration of the circular restricted four-body problem. After determining the equations of motion and quasi-Jacobi integral, we illustrate the locations of stationary points, their stability, Poincare surfaces of section and periodic orbits.
