variable mass of the test particle in the collinear 4-body system with triaxial primaries

The mass variation effect of the test particle is studied in the collinearrestricted four-body configuration with the assumption that the shapes of the threeprimary bodies are triaxial. it is assumed that these three primary bodies are placed inconsecutive order on the abscissa axis and their axes are always parallel to the synodicones. we also consider that the central body have solar radiation effect and the wholesystem is affected by coriolis as well as centrifugal forces. under these assumptions andusing jeans’ law, the equations of motion and quasi-jacobian integral are determined.and hence, the locations of parking points, poincaré surfaces of section, surfaces withprojection and basins of attractions are illustrated for the various values of the variationparameters. furthermore, the stability of the parking points are examined in the inplaneas well as in the out-of-plane.
