Abstract
Since cometary dust interacts with electrons and ions of the surrounding plasma, as well as with solar radiation, the dust becomes charged. As a result, it is possible to treat the medium surrounding the comet nucleus as a dusty plasma. The purpose of the present paper is to discuss plasma-dust processes in comet physics. It is shown that plasma-dust processes can have significant manifestations in the formation of the bow shock formed due to the interaction of the comet’s coma with the solar wind, as well as in situations when the comet is far from the Sun.
期刊介绍：
Fluid Dynamics is an international peer reviewed journal that publishes theoretical, computational, and experimental research on aeromechanics, hydrodynamics, plasma dynamics, underground hydrodynamics, and biomechanics of continuous media. Special attention is given to new trends developing at the leading edge of science, such as theory and application of multi-phase flows, chemically reactive flows, liquid and gas flows in electromagnetic fields, new hydrodynamical methods of increasing oil output, new approaches to the description of turbulent flows, etc.
