A KINETIC CROSS-FIELD STREAMING ELECTROSTATICINSTABILITY FOR TRANSMITTED IONS WITHIN THEBOW SHOCK FRONT
-
摘要: 本文讨论了地球弓激波前内背景电子速度分布函数为平顶形式时的透射离子横场流静电不稳定性.结果表明,在超临界(AlfvénMach数MA>3)准垂直激波区(激波法向与行星际磁场之间的夹角θπB 75°)情况下,透射离子流产生的静电不稳定性增长率峰值要比电子速度为Maxwell分布时更加显著,并满足动力学性质.Abstract: The kinetic cross-field streaming electrostatic instability drivenby transmitted ions in high Alfven Mach number regime within the Earth's bow shock front near quasi-pependicular shocks is studied in this paper. The results show that the maximum growth rate for flat-topped electron distribution are greater than that in the case of Maxwellian distribution.
