       "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 vexp< 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.   |
