Both compressive and rarefactive solitons are found to exist in the unmagnetized dusty plasma in presence of electrons’ drift velocity ( e v ). Comparision with the earlier findings shows that the factor which is responsible for the existence both compressive and rarefactive solitons is the electrons’ drift velocity ( e v ) in the plasma. It is observed that the compressive solitons exist for...

Motivated by the observations of Voyager 1 and 2 spacecraft Freja satellite in Saturn’s magnetosphere, formation dust-acoustic (DA) localized periodic waves a complex plasma having superthermal electrons ions are reported. In this regard, modified Kadomtsev–Petviashvili (mKP) equation is derived employing weak turbulence theory for studying characteristics nonlinear (DAWs) model under considera...

Using Korteweg-de Vries (KdV) equation, solitons are investigated in a dusty plasma consisting of positive ion, negatively charged dust grain and Boltzmann distributed electron. Both compressive and rarefactive solitons are found to exist in the dusty plasma for fast and slow modes. Greater d Z ( d Z is the number of elementary charges residing on the dust grain) is found to yield higher amplit...

Dust acoustic (or dust density) waves have been observed in many laboratory dusty plasmas. These low-frequency waves involve the dynamics of highly charged and massive dust grains, and can be excited by the flow of ions relative to dust. In this paper, we consider the nonlinear development of the dust acoustic instability, excited by thermal ion flow, in a collisional plasma containing dust wit...
