“…Thus, methods for describing and interpreting theoretical studies of physical phenomena depend on finding exact solutions to many types of differential equations. Some well-known evolution equations are non-linear partial differential equations, such as the NLS equation and its generalisations are successfully used to describe non-linear IAWs that are commonly observed in the astronomical environments (Gharaee et al, 2011;Moslem et al, 2019b). To understand the behaviour and properties of different types of wave solutions to non-linear differential equations, investigative analysis must occur due to the increased interest in the field of space research in recent years.…”

The non-linear propagation of different kinds of ion-acoustic waves (IAWs) in multi-component plasma involving proton beam, positive ions and isothermal electrons has been studied. Using the derivative expansion method of basic equations, namely the hydrodynamic and Poisson equations, they are reduced to a single evolution equation of the non-linear Schrödinger (NLS) equation. By applying this model to plasma formed in Earth's magnetosphere, different waves can be predicted that express the properties of the plasma. Using the separating variables method and the G ′ /G-expansion method, we derived the exact analytical solutions to the evolution equation by using different solution regions in which non-linear waves are defined. A comparison has been made between the solutions describing the differential equation in each region in which the solution can appear using the data on the Earth's magnetosphere in the study by Alotaibi et al. (2021).

Slow highly charged ions (HCIs) were used to create a plasma region of nanometer scale on the surface of different materials. The creation of the plasma in a localized region is accompanied by the formation of surface nanostructures. The plasma expansion approach is used to explain the creation mechanism of HCI-induced nanostructures in lithium niobate single crystals, considering the Maxwellian and non-Maxwellian electron distributions. The numerical solutions of the applied hydrodynamic equations show that the profile of the early stage expanded plasma is independent of the ratio of ion-to-electron temperatures. However, an increase in the temperature ratio leads to a wider expansion domain. In addition, the effect of material constituents ions are studied in terms of the modifications induced in the plasma-expanded region.

The observed escape of ions from the ionosphere of Titan suggests a potential role of the solar wind in the interaction with the upper atmospheric layers. We investigate such a plausible scenario using a hydrodynamic fluid approach for the plasma expansion in the upper ionosphere of Titan, combining (Maxwellian) electrons and three different species of positive ions which interact with the solar wind electrons and protons. Using a self-similar transformation, numerical analysis is performed to solve the basic equations, and characterize the plasma density, velocity, and electric potential during the expansion. It is found that increasing the solar wind proton number density leads to a reduction the ion escape, while the effect of electrons is opposite stimulating the ion escape. Moreover, the expansion domain does not change for more energetic protons. The heavier ions has the leading role in controlling the ion escape, i.e. by comparison to CH + 5 ions, C 2 H + 5 ions appear to have a more influence in the loss from Titan ionosphere. For a higher temperature contrast between ions and electrons, the depletion rate of the density increases and the ions move faster, leading to a higher ionic loss.
