Variation in angular momentum (in the inertial frame, top panel) and Jacobi integral (bottom panel) for various sets of prograde/retrograde stellar particles. The individual lines represent variations of median values of quantities as mentioned across six simulation snapshots. Four different sets of stellar particles are depicted here. Particles that keep their prograde or retrograde orbit (marked as PPP and RRR with dotted lines), and those that oscillate between prograde and retrograde direction (denoted as PRP and PRPRPR with solid and dashed lines).
