射电脉冲星的磁层与辐射机制理论

Theories of Magnetosphere and Radiation Mechanism of Radio Pulsar

在本文中先简介强磁场中一些特殊物理过程的特性,在此基础上综述了射电脉冲星的磁层与辐射机制理论。关于磁层,主要由GJ模型出发,从斜转子磁层、加速区机制及回路问题三方面总结前人对磁层问题的认识。关于辐射机制,则侧重于由“相干”问题展开,指出逆康顿散射模型的优势。文末对各种模型作一简单评价。

In this paper, properties of some special processes in strong magnetic fields are brieflyintroduced, and the theories on magnetosphere and radiation mechanism of radio pulsar arereviewed. As to the magnetospheric models, we start with the GJ model, and then deal withthe three important problems: the oblique rotator, the site and the mechanism of particleacceleration, and the current closure problem. As to the radiation mechanism, we focus on the'coherent problem', and point out the advantages of the Inverse Compton Scattering model.Some comments on the models are presented in the end.
