Investigation of chaotic dynamics of near-jupiter neas moving in orbital resonance vicinity
In this paper the investigation results of orbital evolution of asteroids group, near-Earth (NEA) and Jupiter, in the time interval (2014; 3000) years are presented. The group includes 14 NEAs moving in the vicinity of resonances 7/3 with Jupiter. For each of the NEAs the probability motion domains by analyzing the available observations of the object is built. The investigation of possible orbits chaoticity considered NEAs using indicator MEGNO is performed. The calculations were performed by numerical integration of the equations of motion of asteroids in an environment of parallel programming on cluster SKIF CYBERIA TSU using specially developed software and algorithmic.
