Figure 1From: A new hybrid technique for modeling dense star clustersCartoon explanation of the RAPID Code The majority of particles are evolved via the MC approach, with their positions and velocities determined by randomly sampling orbits in the spherical potential of the entire cluster. Meanwhile, a small handful of the most massive objects (the BHs) have their positions and velocities determined by direct N-body integration inside the external potential of the MC stars. Particles from both codes can interact via two-body encounters and strong scattering encounters, allowing energy to flow between the two systemsBack to article page
