Plummer model simulation

This project uses plummer model to simulate star clusters. This model describes a star cluster consists of 10240 stars.

Theoretical part

  1. The inital positions and velocities of all stars is given by Plummer 3D density profile.
  2. Leapfrog integration is used to integrate this hamiltonian system.

Programming part

This project is written in C. Leapfrog integration part is sped up with CUDA.

Simulation result

  1. stable star clusters. If the velocity distribution is set by Plummer model, the star clusters will maintain in a stable status.
  2. unstable star clusters. If the velocity distribution is set randomly, the star clusters will spread out after a while.

Quick Start

  1. clone this repository
git clone https://github.com/CLaigit/plummer_cuda

  1. change the compiler directory in Makefile

  2. compile code compile both unstable cluster and stable cluster

make
  1. run run the stable cluster
./stable.o

run the unstable cluster

./unstable.o
