IV型射电爆发中所谓“斑马”辐射的模型

A model of so-called `Zebra' emissions in type IV radio bursts

R. A. Treumann, R. Nakamura, W. Baumjohann

摘要:

提出了一种简单的产生电磁斑纹辐射的机理。该机制是基于产生的离子环分布在磁镜几何形状中的存在下,一个适当的定向场对齐的电势场。离子回旋脉泽产生一系列电磁离子回旋谐波,这些谐波调制电子脉泽发射。该机制能够准周期性地打开和关闭发射或放大发射,这是观测的主要特征。

英文摘要:

A simple mechanism for the generation of electromagnetic Zebra pattern emission is proposed. The mechanism is based on the generation of an ion-ring distribution in a magnetic mirror geometry in the presence of a properly directed field-aligned electric potential field. The ion-cyclotron maser then generates a number of electromagnetic ion-cyclotron harmonics which modulate the electron maser emission. The mechanism is capable of switching the emission on and off or amplifying it quasi-periodically which is a main feature of the observations.
