Advances in Dusty Plasmas

Effects of adiabatic hot dust on arbitrary amplitude electrostatic solitary structures in magnetoplasmas

“…[1][2][3][4] Dust acoustic solitary waves ͑DASW͒ in unmagnetized [5][6][7][8] as well as in magnetized dusty plasmas 9,10 have been studied by many authors. In dust acoustic waves ͑DAW͒, the restoring force comes from the pressures of inertialess electrons and ions, whereas the dust mass provides the inertia.…”

Solitary solution and energy for the Kadomstev–Petviashvili equation in two temperatures charged dusty grains

“…Hence, numerical studies have been made using plasma parameters close to those values corresponding to Saturn F-ring's i.e., the equilibrium electron and dust densities are n e0 = 10 cm −3 , N h0 = Fig. 5 The variation of the energy of cold and hot charged dusty grains E C , E H with respect to Z h for different values of N h0 for n e0 = 10, n i0 = 10010, m h = m c = 10 12 m i , T i = T e = 1 eV, Z c = 10, N c0 = 8, L = 0.9, and υ 0 = 0.4 10 cm −3 and dust charge and mass are taken as Z h = 10 2 -10 3 , m h = m c = 10 12 m i , respectively, as given in (Akhtar et al 2007;Shukla et al 1997;Mahmood et al 2001;Farid et al 2001). Generally speaking, the present system supports only rarefactive solitons.…”

Amplitude modulation of three-dimensional low-frequency solitary waves in a magnetized dusty superthermal plasma

“…The nonlinear features of solitary waves in dusty plasmas have been of great importance over the last many years due to their wide range of applications in space, astrophysical and laboratory environments [1][2][3]. Dust grains are typically micron or sub-micron sized particles and are ubiquitous ingredients in our universe.…”
