Abstract: | Arbitrary amplitude dust-acoustic double-layers (DA-DLs) in a plasma with suprathermal electrons, two-temperature thermal
ions, and warm drifting dust grains are investigated. Our results reveal that the spatial patterns of the DA-DLs are affected
by the degree of the electron suprathermality. The electron thermalization involves a decrease of the cold ion component density,
for the existence of localized DA-DLs. An increase of the dust drift velocity requires a decrease of κ (the electron spectral index), for the onset of dust-acoustic double-layers. An increase of the Mach number M leads to an increase of the DL amplitude as well as the corresponding electron spectral index for which the DL occurs. |
