Main Features of Dynamical Escape from ThreeDimensional Triple Systems
Abstract
The dynamical evolution of triple systems with equal and unequalmass components and different initial velocities is studied. It is shown that, in general, the statistical results for the planar and threedimensional triple systems do not differ significantly. Most (about 85%) of the systems disrupt; the escape of one component occurs after a triple approach of the components. In a system with unequal masses, the escaping body usually has the smallest mass. A small fraction (about 15%) of stable or longlived systems is formed if the angular momentum is nonzero. Averages, distributions and coefficients of correlations of evolutionary characteristics are presented: the lifetime, angular momentum, numbers of wide and close triple approaches of bodies, relative energy of escapers, minimum perimeter during the last triple approach resulting in escape, elements of orbits of the final binary and escaper.
