  A multi-species magnetized collisional nonthermal plasma system containing
inertial ion species, non-inertial electron species following nonthermal
kappa-distribution, and immobile dust particles are considered to model the
dissipative dust-ion-acoustic (DIA) soliton modes, both theoretically and
numerically. The electrostatic solitary modes are found to be associated with
the low frequency dissipative dust-ion-acoustic solitary waves (DIASWs). The
ion-neutral collision is taken into account, and the influence of ion-neutral
collisional effects on the dynamics of dissipative DIASWs is investigated. It
is reported that most of the plasma medium in space and laboratory are far from
thermal equilibrium, and the particles in such plasma system are well fitted
via the kappa-nonthermal distribution than via the thermal Maxwellian
distribution. The reductive perturbation approach is adopted to derive the
damped KdV equation, and the solitary wave solution of the damped KdV equation
is derived via the tangent hyperbolic method to analyze the basic features
(amplitude, width, speed, time evolution, etc.) of dissipative DIASWs. The
propagation nature and also the basic features of dissipative DIASWs are seen
to influence significantly due to the variation of the plasma configuration
parameters and also due to the variation of the supethermality index kappa in
the considered plasma system. The implication of the results of this study
could be useful for better understanding the electrostatic localized
disturbances, in the ion length and time scale, in space and experimental dusty
plasmas, where the presence of excess energetic electrons and ion-neutral
collisional damping are accountable.
