| Research Abstract |
Outflows with relativistic speed appear in various astrophysical objects such as pulsars, gamma-ray bursts and accretion disks around a black hole. Strong magnetic field has been considered to be an important role on them, but theoretical understanding of the actual mechanism still remains. During the period supported by this Grant-in-Aid for Scientific Research, two major results are achieved. One is numerical construction of pulsar magnetosphere in terms of two-fluid approximation for the plasma. The other is the study of magnetic reconnection in highly magnetized situation. It is pointed out that the rate depends on the magnetic Reynolds number and magnetized parameter.
