abstract = {<p style="text-align: justify;">In this study, an <span style="font-family: ">N</span>-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 execution,
and it could be accelerated by several tens of times compared to a single-core
CPU for <span style="font-family: ">N</span> ≃10<sup>4</sup> objects.</p>},
