文摘

Electron-positron pairs will be produced from vacuum when high-energy emissions propagate through the magnetized pair plasmas of pulsars. These pairs then move under the action of strong electromagnetic fields, and emit electromagnetic radiations. Firstly, the property of radiation fields emitted by the pairs is discussed using Maxwell equations and Boltzmann-Vlasov equation. Then the quantum character of the pairs is examined, and the frequency and luminosity of radiations emitted by the pairs are obtained.
