This is a model of interacting objects. Losses by friction are absent. The interaction is implemented according to the inverse-radius law, and at small distances attraction is replaced by repulsion.
The configuration is three stars with a common belt of asteroids. The configuration of the objects doesn't stabilize with time. The configuration is not stable, however no objects fly away to infinity. Such behavior is defined by the fact that the corresponding potential increases without limit at infinity. This model is an example of the system that is located in an infinitely deep potential well.
