Dynamical study of nonlinear ion acoustic waves in presence of charged space debris at Low Earth Orbital (LEO) plasma region

Accelerated magnetosonic lump wave solutions by orbiting charged space debris

“…The experimental observation of modifications in the propagation characteristics of precursor solitons caused by different shapes and sizes of the object over which the dust fluid flows are reported in [14]. In our previous works [6,7] on space debris, pinned accelerated and curved solitary wave solutions due to space debris motion are discussed; providing a detailed understanding of the dynamical properties of solitary waves in the LEO region in (1 + 1) and (2 + 1) dimensions. In these works, we discuss an indirect detection technique for orbital debris objects by observation of changes in amplitudes and velocities of solitary waves.…”

“…Therefore, to avoid these deteriorating effects, active debris removal (ADR) has become a challenging problem in the twenty-first century. Some indirect detection techniques of the space debris have also been developed by different authors [5][6][7][8]. Recently, a detailed investigation of solitons generated due to orbital space debris motion has been carried out by Truitt and Hartzell [9,10] through simulations using forced Korteweg-de Vries (KdV) equation and damped forced Kadomtsev-Petviashvili (KP) equations.…”

“…This work of Kumar and Sen is performed through particle in cell (PIC) simulations; along with the approximation of the ambient magnetic field in Z direction only, which is not more realistic as desired. For dealing with these hydromagnetic waves, a magnetohydrodynamics (MHD) model will be useful rather than simple fluid models as done in [5][6][7]. In particular, for explorations in space and astrophysical conditions involving magnetized plasmas, Hall MHD model is extremely useful; which takes into account the Hall current generated in the magnetized plasma behaving as a dielectric medium.…”

Charged space debris induced nonlinear magnetosonic waves using inertial magnetohydrodynamics

“…In our most recent work [4] on space debris, ambient magnetic field in the LEO region is considered analytically to determine debris dynamics in the framework of Hall MHD; where we have detected accelerated magnetosonic lump solutions accompanied with changes in their amplitudes. Therefore, 1D solitary waves generated due to space debris as reported in [1,2,6] are liable to show lump like behaviours in two dimensions. In addition, there can also be possibilities of obtaining planar and ring solitons due to debris as reported in [3,7] that may be associated with special features like bending in spatial dimensions and time-dependent velocities showing accelerating behaviours.…”

“…In this regard, research on dynamics of space debris particles that are ubiquitous in near-Earth space has gained optimum importance during recent times. There have been many theoretical, computational and equivalent experimental investigations of space debris dynamics in near-Earth space plasma environment [1][2][3][4][5][6][7][8][9] done in recent years. The motion of charged space debris and its interaction with the surrounding plasma in ionosphere can give rise to various types of nonlinear structures such as precursors and solitons with electrostatic and electromagnetic characteristics.…”
