Nonlinear solitary oscillations in a varying charge dusty plasma in the presence of nonisothermal trapped electrons

Our recent analysis [Tribeche M, Zerguini TH, Aoutou K. Nonlinear oscillations in dusty plasmas in the presence of nonisothermal trapped electrons. Phys Plasmas 2003;10:631] is extended to include self-consistently the dust charge variation. The grain charge becomes a new self-consistent dynamical variable, leading to some new and interesting results.
