Abstract
The ion density and electric potential distribution around a dust particle in a plasma with flowing ions are found analytically from a linear kinetic approach for sub- and supersonic ion flows in the collisional and collisionless regimes. From this the different momenta of the ion density distribution are derived. Oscillatory potential distributions obtained in previous studies are shown to be suppressed even in the collisionless situation.
