| Outline of Final Research Achievements |
I developed a basic numerical code for Particle-in-simulation for investigating particle acceleration mechanism in the pulsar magnetosphere which transits one current to another current value. In particular, the code enable us to treat properly the boundary condition which can change current density. For the application to the QED effect, I also make experiment for electron-positron pair creation to find a good result.
In order to compare the result with observation, I studied the X-ray luminosity and find that a hidden correlation between the X-ray luminosity and the rotation power of the pulsars.
