A Particle Simulation for the Global Pulsar Magnetosphere: the Pulsar Wind linked to the Outer Gaps
Soon after the discovery of radio pulsars in 1967, the pulsars are identified as strongly magnetic (typically 10G) rapidly rotating (∼ 10−0.1 Hz) neutron stars. However, the mechanism of particle acceleration in the pulsar magnetosphere has been a longstanding problem. The central problem is why the rotation power manifests itself in both gamma-ray beams and a highly relativistic wind of electr...
متن کاملPolarization transfer in pulsar magnetosphere
Propagation of radio waves in the ultrarelativistic magnetized electronpositron plasma of pulsar magnetosphere is considered. Polarization state of the original natural waves is found to vary markedly on account of the wave mode coupling and cyclotron absorption. The change is most pronounced when the regions of mode coupling and cyclotron resonance approximately coincide. In cases when the wav...
متن کاملThe Disturbance of a Millisecond Pulsar Magnetosphere
Pulsar timing has enabled some of the strongest tests of fundamental physics. Central to the technique is the assumption that the detected radio pulses can be used to accurately measure the rotation of the pulsar. Here we report on a broad-band variation in the pulse profile of the millisecond pulsar J1643−1224. A new component of emission suddenly appears in the pulse profile, decays over 4 mo...
متن کاملPulsar shade – discovery of inward emission in pulsar magnetosphere
We present the theory of eclipsing a rotating, spatially extended source of directional emission by a central absorber, and apply it to the pulsar magnetosphere. The theory assumes the radially extended inward radio emission along the local direction of magnetic field, and the pulsar as the absorber. Geometry of magnetic field lines of the rotating dipole is favourable for the double eclipse ev...
متن کاملOn the Axisymmetric Force-free Pulsar Magnetosphere
We investigate the axisymmetric magnetosphere of an aligned rotating magnetic dipole surrounded by an ideal force-free plasma. We concentrate on the magnetic field structure around the point of intersection of the separatrix between the openand closed-field line regions and the equatorial plane. We first study the case in which this intersection point is located at the light cylinder. We find t...
