WebThe plasma (electron) density in ionosphere changes in a year and is dependent on solar activity (in terms of sunspot relative number). The plasma frequency μpe is expressed as follows: (1) where Ne is electron density and me is electron mass. Web11 apr. 2024 · The effect of dust grain pressure on the head-on collision of two dust-acoustic solitary waves in non-magnetized, collisionless, and strongly coupled dust plasma has been investigated [J. Plasma Phys. (2024), 86, 905,860,111].In this paper, the model is augmented by incorporating the ion drag force on dust grains.
