蟹状星云脉冲星:离子-质子等离子体和高频射电频谱

The Crab pulsar: ion-proton plasma and high-frequency radio spectrum

P B Jones

摘要:

总结了蟹状星云脉冲星高频脉冲间的显著能带结构的显著特征。它的源必须位于一个电流片中,可能与开闭磁层分界线重合,其机制是一种单程自由电子激光。电流片中向外移动的电子分量与向内定向的离子-质子朗缪尔模式的纵向电场相互作用。因此,能带结构是离子不同荷质比的自然结果,这些荷质比是从极冠到光柱的加速离子的返回电流分量,几乎所有的质子都是如此。

英文摘要:

Salient features of the remarkable band structure seen in the high-frequency interpulse of the Crab pulsar are summarized. It is argued that its source must lie in a current sheet, probably coincident with the open-closed magnetosphere separatrix, and that the mechanism is a form of one-pass free-electron laser. An outward moving electron component in the current sheet interacts with the longitudinal electric field of an inward directed ion-proton Lamgmuir mode. The band structure is then a natural consequence of the differing charge-to-mass ratios of the ions, which are a return current component of those accelerated, as in almost all pulsars, from the polar cap to the light cylinder.
