The effect of an external magnetic field on a critical point for phase transitions in a dusty plasma is investigated. It is shown that the ambient magnetic field increases the effective hard core radius of dust particles, which, in turn, would affect a critical point in terms of the Coulomb coupling parameter and the ratio between the inter-dust grain spacing and the dusty plasma Debye radius. ...

A review is presented of recent experiments performed on the University of Iowa DC discharge dusty plasma device on various aspects of dust acoustic waves. A brief introduction to the physics of dusty plasmas and the dust acoustic wave is first presented. Three experiments are then described: (i) observation and interpretation of large amplitude (nonlinear) dust acoustic waves; (ii) evolution o...

Abstract Dusty Casson fluids and tetra-hybrid nanofluids are complex phenomena that find their extensive uses in engineering industrial applications. For instance, dusty used gas-freezing systems nuclear power reactors. The main objective of this article is to focus on the characterization generalized two-phase free convection magnetohydrodynamic flow nanofluid among parallel microplates: fluid...

We re-address the classification criterion for extremely red galaxies (ERGs) of Pozzetti & Mannucci (2000 – PM00), which aims to separate, in the Ic − K (or Rc − K) vs. J−K colour–colour diagram, passively evolving, old (> 1 Gyr) stellar populations in a dust-free environment, associated with ellipticals (Es), from dusty starburst galaxies (DSGs), both at 1 < z < 2. We explore a category of obj...

Introduction Plasmas with dust grains are of interest both for the cosmic space as well as for the laboratory plasmas. Examples include cometary environments, planetary rings, the interstellar medium, the Earth’s and other planets magnetospheres [1]. Dust has been found to be a determinant component of rarefied plasmas used in the microelectronic processing industry [2], and it may also be pres...
