Curvature radiation in pulsar magnetospheric plasma
We consider the curvature radiation of the point-like charge moving relativistically along curved magnetic field lines through a pulsar magnetospheric electron-positron plasma. We demonstrate that the radiation power is largely suppressed as compared with the vacuum case, but still at a considerable level, high enough to explain the observed pulsar luminosities. The emitted radiation is polariz...
متن کاملPair Creation and Plasma Oscillations *
We describe aspects of particle creation in strong fields using a quantum kinetic equation with a relaxation-time approximation to the collision term. The strong electric background field is determined by solving Maxwell’s equation in tandem with the Vlasov equation. Plasma oscillations appear as a result of feedback between the background field and the field generated by the particles produced...
متن کاملBeam Instabilities in Magnetized Pair Plasma
Beam instabilities in the strongly magnetized electron-positron plasma of pulsar magnetospheres are considered. We analyze the resonance conditions and estimate the growth rates of the Cherenkov and cyclotron instabilities of the ordinary (O), extraordinary (X) and Alfvén modes in two limiting regimes: kinetic and hydrodynamic. As a preliminary step, we reconsider wave dispersion and polarizati...
متن کاملTwo-photon annihilation in the pair formation cascades in pulsar polar caps
The importance of the photon-photon pair production process (γ + γ′ → e+ + e−) to form pair production cascades in pulsar polar caps is investigated within the framework of the Ruderman-Sutherland vacuum gap model. It is found that this process is unimportant if the polar caps are not hot enough, but will play a non-negligible role in the pair formation cascades when the polar cap temperatures ...
متن کاملDark Solitons in Gravitational Wave and Pulsar Plasma Interaction
The nonlinear propagation of gravitational wave perpendicular to a superstrong magnetic field immersed in electron-positron pulsar plasma is considered. It is found that a weak gravitational wave resonates an effective field perturbation in the strongly magnetized pulsar plasma. The slowly varying field amplitude obeys the nonlinear Schrödinger equation, the solution of which is the dark solito...
