摘要:

本文提出了一种大尺度磁场环向分量的产生机制,它导致了脉冲星磁层的重建。为了了解磁场线的扭曲,我们研究了脉冲星磁层中旋转的等离子体流的运动学。通过研究描述相对论等离子体流动行为的精确方程组,导出了曲率漂移不稳定性的增量,并对$1s$类星体进行了估计。结果表明,一种新的参量机制是非常有效的,可以解释脉冲星磁层中的旋转能量泵。

英文摘要:

A mechanism of generation of a toroidal component of large scale magnetic field, leading to the reconstruction of the pulsar magnetospheres is presented. In order to understand twisting of magnetic field lines, we investigate kinematics of a plasma stream rotating in the pulsar magnetosphere. Studying an exact set of equations describing the behavior of relativistic plasma flows, the increment of the curvature drift instability is derived, and estimated for $1s$ pulsars. It is shown that a new parametric mechanism is very efficient and can explain rotation energy pumping in the pulsar magnetospheres.
