Looking 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 کاملElectrodynamics 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 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...
متن کاملInduced Raman Scattering in Pulsar Magnetospheres
It is shown that induced Raman scattering of electromagnetic waves in the strongly magnetized electron-positron plasma of pulsar magnetosphere may be important for wave propagation and as an effective saturation mechanism for electromagnetic instabilities. The frequencies, at which strong Raman scattering occurs in the outer parts of magnetosphere, fall into the observed radio band. The typical...
متن کاملTwo-stream Instability in Pulsar Magnetospheres
Creation of electron-positron pairs near the pulsar surface and the parameters of plasma in pulsar magnetospheres are discussed. It is argued that the pair creation process is nonstationary, and the pair plasma that flows out from the pulsar environment is strongly nonhomogeneous and gathers into separate clouds. Plasma instabilities in the outflowing plasma are reviewed. The two-stream instabi...
