"Model of ejection of matter from nonstationary dense stellar clusters and chaotic motion of gravitating shells"

M.V. Barkov (IKI)

Abstract:

It is shown that during the motion of two initially gravitationally bound spherical shells, consisting of point particles moving along ballistic trajectories, one of the shell may be expelled to infinity at sub relativistic speed v_exp< 0.25 c. The problem is solved in Newtonian gravity and GR. Motion of two intersecting shells in the case when they do not runaway shows a chaotic behavior.
