摘要
考虑由脉冲星碰偶极辐射产生的低频电磁波,它构成的湍动波压将加速等离子体,并通过磁极的磁力线散发到空间,形成脉冲星风.计算表明:当找到一个能与粒子产生共振的初始波能时,电子可被加速到γ≥12,而构成相对论性风流.
It is considered that the acceleration process of plasma was driven by the turbulent wave pressure generated with the magnetic dipole radiation of pulsar. The plasma particlesdiffused along magnetic line of force and formed pulsar winds. The calculation illustratedthat electrons were accelerated to high energy of Lorenz fator γ≥12 and formed relativisticwinds, finding the only beginning energy of wave which made electrons resonate.
