含超热电子的暖磁等离子体中的离子声孤子

Ion-acoustic solitons in warm magnetoplasmas with super-thermal electrons

B. Choudhury, R. Goswami, G. C. Das, M. P. Bora

摘要:

在这项工作中,局部静电波(ESW)或孤立子的形成的现象被认为是在一个温暖的磁等离子体与非热电子分布的可能性。这里考虑的参数制度是相关的磁层等离子体的情况下。我们发现,偏离通常的放松麦克斯韦分布的电子布居有一个显着的轴承在允许的参数制度,在这些ESW可以找到。我们进一步考虑存在一个以上的电子温度,这是最近的天基观测的启发[key-2]。

英文摘要:

In this work, the phenomenon of formation of localised electrostatic waves (ESW) or soliton is considered in a warm magnetoplasma with the possibility of non-thermal electron distribution. The parameter regime considered here is relevant in case of magnetospheric plasmas. We show that deviation from a usual relaxed Maxwellian distribution of the electron population has a significant bearing in the allowed parameter regime, where these ESWs can be found. We further consider the presence of more than one electron temperature, which is inspired by recent space-based observations[key-2].
