What is it about?
Studying magnetic reconnection (MR) is important owing to it's impact on the space weather and fusion reactors. Plasma waves are a good candidate to study the characteristics of MR since they can regulate the particle flux and carry messages from far plasmas.

Why is it important?
In this paper, we revealed the characteristics of the correlation between solitary waves and the counter-directed electron beam at the magnetic reconnection region in the Earth’s magnetotail. Moreover, the fluid model has been utilized to address the mechanism behind the observation of soliton waves in the solar wind at 1au. In the case of the Earth’s magnetosphere, we consider the plasma to consist of fluid ions, cold electron beam, and superthermal background electrons. For the solar wind, we considered the plasma to consist of streaming protons, fluid alpha particles, and superthermal electrons. The calculated electric field using the current model and the measured electric field in the Earth’s magnetosphere and solar wind are highlighted.
