WebA dusty plasmais a plasmacontaining micrometer (10−6) to nanometer (10−9) sized particles suspended in it. Dust particles are charged and the plasma and particles behave as a plasma. [1][2]Dust particles may form larger particles resulting in "grain plasmas". WebA typical dust devil on Earth spans a few meters to tens of meters in diameter, with a height 5 to 20 times as large. Its height is capped by the top of the planetary boundary layer (PBL), usually between 0.2 km and 2 km thick, where air can mix in contact with the ground.
WebWe all know that the energy-momentum tensor for dust is just T α β = ρ 0 v α v β, where ρ 0 is the mass density in the dust's rest frame and v α is the dust's four-velocity. I'm trying to derive the dust energy momentum tensor from the equation T α β = − 2 − g δ S M δ g α β but I'm getting the wrong answer. The action for dust is
