文摘In this study,an N-body simulation code was developed for self-gravitating systems with a limited first-order post-Newtonian approximation.The code was applied to a special case in which the system consists of one massive object and many low-mass objects.Therefore,the behavior of stars around the massive black hole could be analyzed.A graphics processing unit(GPU)was used to accelerate the code exe-cution,and it could be accelerated by several tens of times compared to a single-core CPU for N≃104 objects.
