Linearized periodic orbits around collinear Libration points in the ER3BP with albedo of both, an oblate primary and a Triaxial secondary surrounded by a belt

This paper investigates the motion of an infinitesimal mass (test particle) around Lagrangian collinear equilibrium points L 1 , 2 , 3 in the frame work of the Elliptic Restricted Three-Body Problem (ER3BP) under the influences of albedo (reflected radiation) of both, an oblate primary and a triaxial secondary surrounding them a belt. It is observed that the positions of the points L 1 , 2 , 3 depend on the combined effect of albedo, oblateness, triaxiality and the potential due to the belt. An increase in any of these parameters produces shifts towards or away from the origin in the classical locations of points L 1 , 2 , 3 . It is also found that the equilibrium points remain linearly unstable, but stable periodic orbits in their neighbourhood may still exist for certain parameter ranges. .
