Particle simulation of the global pulsar magnetosphere

Particle simulation has been applied to understand the activity of the pulsar magnetosphere in use of the special purpose computer for gravitational N-body problem. We confirm the existence of the outer gap, which is a linear-accelerator in the magnetosphere. If electron-positron pair creation is induced, the magnetosphere becomes to have winds with trans-field drift motion by radiation drag. We suggest that the basic activities of the pulsar magnetosphere, gamma-ray pulses and pair winds, can be understood by the global particle simulation. (author)
