Electrodynamics of pulsar magnetospheres
I review the theoretical understanding of the global structure of pulsar magnetospheres concentrating on recent progress in force-free electrodynamics and first-principles simulations of magnetospheres.
متن کاملLooking into Pulsar Magnetospheres
Diffractive and refractive magnetospheric scintillations may allow a direct testing of the plasma inside the light cylinder. Unusual electrodynamics of the strongly magnetized electron-positron plasma allow separation of the magnetospheric and interstellar scattering. The most distinctive feature of the magnetospheric scintillations is their independence on frequency. Diffractive scattering due...
متن کاملLinear Transformation and the Escape of Waves from Pulsar Magnetospheres
Two-stream instability in pulsar magnetospheres generates longitudinal waves, which fall in the superluminal part of the dispersion curve due to stimulated scattering. A superluminal longitudinal wave propagating in a curved magnetic field turns into an electromagnetic wave and may escape from plasma in the form of an ordinary transverse wave. However, this wave may go to the subluminal part of...
متن کاملPolarization Patterns in Pulsar Radio Emission
A variety of intriguing polarization patterns are created when polarization observations of the single pulses from radio pulsars are displayed in a twodimensional projection of the Poincaré sphere. In many pulsars, the projections produce two clusters of data points that reside at antipodal points on the sphere. The clusters are formed by fluctuations in polarization amplitude that are parallel...
متن کاملPropagation effects in pulsar magnetospheres
Refraction and polarization transfer in an ultrarelativistic highly magnetized pulsar plasma are considered. Normal waves in the pulsar plasma are linearly polarized however circular polarization arises in the polarization limiting region if radiation propagates at an angle to the plane of the magnetic field lines. The rays go off this plane due to refraction or (and) due to rotation of the mag...
