Abstract

Direct N-body simulation is hard to implement as the great demand on computational resources. It is strictly relied on the configurations of hardware and software. The direct N-body simulation of star clusters are important for many scientific projects including the China Space Station Telescope (CSST), because star clusters are important celestial bodies of these projects. Such simulation is difficult to be done by normal computers because of the large number of cluster member stars. This paper carries out the direct N-body simulation of three globular cluster models for CSST. The cluster models take various star numbers, binary fractions and chemical compositions. The simulation is realized via employing appropriate environment configuration and an updated code, NbodyCP, which is based on NBODY6++GPU. The photometric data, spatial and physical parameters of three clusters are finally calculated. It is shown that GPU computational technique and the number of binaries dominate the computational efficiency of celestial bodies with a large amount of member stars.
