Abstract

The dynamics of a massive binary System in a galactic nucleus are presented. These are the first results from simulations applying a hybrid "self consistent field" (SCF) 1 and direct Aarseth N body integrator (NBODY6) 2, which synthesises the advantages of the direct force calculation with the efficiency of the field method. The code is aimed for use on parallel architectures and is therefore applicable for collisional N-body integrations with extraordinarily large particle numbers (> 105). It opens the perspective to simulate the dynamics of globular clusters with realistic collisional relaxation, as well as stellar Systems surrounding a supermassive black hole in galactic nuclei.
