The planetary and lunar ephemerides called DE440 and DE441 have been generated by fittingnumerically integrated orbits to ground-based and space-based observations. Compared to theprevious general-pur
In this paper we report on the feasibility of light confinement in orbital geodesics on stationary, planar, and centro-symmetric refractive index mappings. Constrained to fabrication and [meta]materia

Abstract The three-body problem deals with point objects interacting mutually through Newton's gravitational force. For more than three centuries, the study of this type of system has led to the devel
