摘要：
Nuclear Stellar Clusters are so dense stellar systems (containing up to 10(7) stars in few parsec radius) that their dynamics cannot be followed with the high precision, direct summation available N-body codes over a long integration time. Here we present the main idea of our new computational approach to study the dynamics of the MW NSC exploiting the facilities of the high precision hybrid parallelized code NBODY6++GPU. This strategy will allow us to study the evolution of the NSC over its 2-body relaxation time with an acceptable numerical effort by mean of a massive computational platform.
