Box orbit
In stellar dynamics , a box orbit describes a certain type of orbit that occurs in triaxial systems. These are systems that have no symmetry about one of their coordinate axes . The box orbits are therefore counterparts to the loop orbits that occur in spherically symmetrical or axially symmetrical systems.
In a box orbit , the star oscillates independently along three different axes as it moves through the system. As a result of this movement, it occupies roughly a box-shaped region in space. In contrast to the Loop Orbit, the stars on Box Orbits can come as close as desired to the center of the system. In a special case, if the frequencies of the oscillation are commensurable in different directions , the orbit will lie on a one or two-dimensional manifold and can avoid the center. Such orbits are sometimes called " boxlets ".
