Plasmas Damping solitary wave in dusty plasma is studied by considering the collision effect between dust grains and ions. It can be described by a KdV type equation in which a damping term of u 2 exist. It is found that both the amplitude and propagation velocity of the solitary wave decrease with time exponentially. Our results are compared with another KdV type equation with the damping term of u. It is noted that the damping rate of the KdV type equation with the damping term of u 2 is larger than that with the term of u. It is found that the damping rate is proportional to the collision frequency between dust grains and ions. V C 2012 American Institute of Physics.

Soliton solutions and chaotic motion of the extended Zakharov-Kuznetsov equations in a magnetized two-ion-temperature dusty plasma

“…11 Linear properties of the dust-ion-acoustic waves have been observed in the laboratory. 12 Certain nonlinear features of the dust-ion-acoustic waves in the dusty plasmas have been studied numerically. 13 Considering a four-component dusty plasma consisting of dust particles which are extremely massive and usually negatively charged, electrons, high-temperature ions, and lowtemperature ions in the presence of an external static magnetic field M, people have assumed that there are N different species of dust grains whose masses are m dj 's ðj ¼ 1; 2; …; NÞ and sizes are different.…”

Alfvén waves in space and astrophysical dusty plasmas

“…In a collisional dusty plasma the damping rate is found to be proportional to the collision frequency between dust and ions (Yang et al, 2012). It has been shown by many authors (Khan et al, 2013;Zubia et al, 2007) that the collisionless Landau damping is negligibly small for nearly perpendicular propagation (small k ), while dust charge fluctuation damping is the main mechanism for the damping of kinetic Alfvén waves, which could be a reason for plasma heating.…”

Dust Ion Acoustic Solitary Waves in Unmagnetized Plasma with Kaniadakis Distributed Electrons

“…The detailed description of the aforementioned new acoustic modes seen in Refs. [8][9][10][11][12][13][14][15][16][17][18][19][20][21] has a unique value in astrophysical phenomena. The physical mechanism involved in DIAWs is similar to the IAWs, wherein the restoring force is provided by the inertialess electron while inertia comes from the ion mass.…”
