摘要：
The ion acoustic solitary waves in the presence of hot ions have been found in unmagnetized dusty plasmas using Sagdeev potential approach. It is found that both ion density humps and dips corresponding to positive and negative value of the electrostatic potential can coexist in such systems. It is shown that ion thermal energy reduces the wave amplitude and also decreases the Mach number regime.
