Abstract Considering the variation of dust charges, We have analytically studied the governing equation for the system with the same model as that for cold dust acoustic waves in a demagnetized plasma but the contribution of hot dust. The result indicates that the governing equation is also a Korteweg-de Vries equaiton, although its amplitude and width will be smaller compared with the cold dust case.
