Nonlinear propagation of ionacoustic waves in a selfgravitating
dusty plasma consisting of warm positive ions,
isothermal twotemperature electrons and negatively charged dust
particles having charge fluctuations is studied using the reductive
perturbation method. It is shown that the nonlinear propagation of
ionacoustic waves in such plasma can be described by an uncoupled
third order partial differential equation which is a modified form of
the usual KortewegdeVries (KdV) equation. From this nonlinear
equation, a new type of solution for the ionacoustic wave is
obtained. The effects of twotemperature electrons, gravity and dust
charge fluctuations on the ionacoustic solitary waves are discussed
with possible applications.
