Using a Sagdeev pseudopotential approach where the nonlinear structures arestationary in a comoving frame, the arbitrary or large amplitude dust-acousticsolitary waves and double layers have been studied in dusty plasmas containingwarm positively charged dust and nonthermal distributed electrons and ions.Depending on the values of the critical Mach number, which varies with theplasma parameter, both supersonic and subsonic dust-acoustic solitary waves arefound. It is found that our plasma system under consideration supports bothpositive and negative supersonic solitary waves, and only positive subsonicsolitary waves and negative double layers. The parametric regimes for theexistence of subsonic and supersonic dust-acoustic waves and how the polarityof solitary waves changes with plasma parameters are shown. It is observed thatthe solitary waves and double layers solution exist at the values of Machnumber around its critical Mach number. The basic properties (amplitude, width,speed, etc.) of the solitary pulses and double layers are significantlymodified by the plasma parameters (viz. ion to positive dust number densityratio, ion to electron temperature ratio, nonthermal parameter, positive dusttemperature to ion temperature ratio, etc.). The applications of our presentwork in space environments (viz. cometary tails, Earth's mesosphere, Jupiter'smagnetosphere, etc.) and laboratory devices, where nonthermal ions andelectrons species along with positively charged dust species have beenobserved, are briefly discussed.
