Abstract

A distribution of the electric potentials around a charged absorbing particle in a drifting weakly ionised collisional plasma with negative ions is calculated in the linear hydrodynamic approach. Coulomb-like asymptote of the electric potential around the absorbing particle deforms under the action of the negative ions’ flow and exhibits a valley profile along the flow behind the particle. The presence of the flowing negative ions can be conducive to string formation in the dust structures at relatively large pressures.
