Abstract :
[en] Using the fluid dynamic paradigm, we study acoustic solitons in a dusty plasma with two ion temperatures, using a polytropic equation of state. On the ion-acoustic timescale we consider a four-component plasma, with super-hot electrons and massive dust grains. We find existence regimes for both positive and negative potential solitons and double layers. For dust-acoustic solitons, we consider a three-component plasma, with no free electrons, and "super-hot" hot ions. This model supports both positive and negative potential solitons, unlike a dust-ion-electron plasma, that allows only negative solitons
