Abstract [en]

Arbitraryamplitude dust ion-acoustic shock waves in a multi-ion dusty plasma(composed of electrons, light positive ions, heavy negative ions, andstationary massive dust grains) has been studied. For this purpose,the coupled Poisson and dust-charging equations, which accounts for thefluctuation of charges on static dust, have been numerically solved.The large amplitude shocks are associated with a sudden decreasein the electrostatic potential and of the dust grain charge.It is found that in the lower speed limit smallamplitude shocks are formed, while in the larger speed limitlarge amplitude shocks are formed. It is anticipated that theprofiles and amplitudes of the DIA shocks predicted here willbe observed in forthcoming laboratory and space experiments.
