Gamma-ray emission from Outer-Gap of pulsar magnetosphere
Junpei Takata, Sinpei Shibata, Kouichi Hirotani
We develop a model for gamma-ray emission from the outer magnetosphere of pulsars (the outer-gap model). The charge depletion causes a large electric field which accelerates electr…

On the Field-Aligned Particle Acceleration in the presence of Electron-Positron Pairs
S. Shibata, J. Miyazaki, F. Takahara
We study self-consistency for the pulsar polar cap model. In general, there will remain an unscreened electric field at the pair production front (PPF). We have derived the conditi…
