论文摘要
地球磁层中孤立波的起源和太阳风，尤其是接近磁性重新连接区域，仍然是一个悬而未决的问题。为此，我们使用流体模型来获得具有多种组分的空间等离子体中孤立波的形成背后的机制。我们的发现表明，在地球磁尾的磁重新连接的分离下，反射的电子束会导致脉冲振幅的扩大。在增加电子束的同时，正速度会导致孤子振幅增加一点。此外，我们观察到，孤子轮廓对等离子体参数非常敏感，例如密度和温度。强调了使用当前模型和地球磁层和太阳风中测得的电场计算出的电场。
The origin of the solitary waves in the Earth's magnetosphere and the solar wind, particularly close to the magnetic reconnection regions, is still an open question. For that purpose, we used the fluid model to obtain the mechanism behind the formation of solitary waves in space plasmas with a variety of components. Our findings reveal that at the separatrix of the magnetic reconnection in the Earth's magnetotail, the counter-ejected electron beam leads to a broadening of the pulse amplitude. While increasing the electron beam positive velocity causes a bit increase in the soliton amplitude. Moreover, we observed that the soliton profile is very sensitive to the plasma parameters like density and temperature. The calculated electric field using the current model and the measured electric field in the Earth's magnetosphere and solar wind is highlighted.
