| Abstract: | In this paper,a KdV equation which described the dust-acoustic solitary waves in an unmagnetized hot dusty plasma with two-temperature nonthermal distributed ions was derived by using the reductive perturbation method.It was found that the dust fluid temperature might change the nature of the dust-acoustic solitary waves and might support the coexistence of compressive and rarefactive solitary waves. |
