Query: Accelerated magnetosonic lump wave solutions by orbiting charged space
  debris   The excitations of nonlinear magnetosonic lump waves induced by orbiting
charged space debris objects in the Low Earth Orbital (LEO) plasma region are
investigated in presence of the ambient magnetic field. These nonlinear waves
are found to be governed by the forced Kadomtsev-Petviashvili (KP) type model
equation, where the forcing term signifies the source current generated by
different possible motions of charged space debris particles in the LEO plasma
region. Different analytic lump wave solutions that are stable for both slow
and fast magnetosonic waves in presence of charged space debris particles are
found for the first time. The dynamics of exact pinned accelerated lump waves
is explored in detail. Approximate lump wave solutions with time-dependent
amplitudes and velocities are analyzed through perturbation methods for
different types of localized space debris functions; yielding approximate
pinned accelerated lump wave solutions. These new results may pave new
direction in this field of research.
