Non-Gaussian distributions in solar wind plasma: data analysis and source

Abstract

While trying to arrive at the four-picket pulse shape, the author of this work accidently found a very interesting result. Specifically, it is found that not only four-picket pulse can be formed from combination of two or more Maxwell distributions but additionally several non-Maxwellian distributions can be generated. This result is very attractive and physically acceptable. Because, systems having two types of distributions will go to a third state that is non-equilibrium state, meaning that two Maxwellian distributions will give a third distribution and so on. Our results are significant for plasma systems connected to external energy source such as solar wind.
