Collisionless shock wave
WebMar 23, 2016 · Collisionless shocks are shock wave systems in which interactions between the different components are mediated by electromagnetic forces. These interactions involve a great variety of electromagnetic fluctuations that are triggered by a great variety of sources of free energy, all of them being at some stage connected with … WebOct 6, 2015 · Niemann et al. have now made measurements of collisionless shock waves in the lab. In a normal shock wave, as the gas compresses, the particles “collide”—that is, they get so close that ...

WebSep 16, 2009 · A comprehensive review is given of the theory and properties of nonrelativistic shocks in hot collisionless plasmas—in view of their possible application in astrophysics. Understanding non-relativistic collisionless shocks is an indispensable step towards a general account of collisionless astrophysical shocks of high Mach number … WebJun 13, 2024 · The clash of two galaxy clusters in Abell 2146 is teaching astronomers about the kinds of "collisionless" shock waves that occur in our own solar system. Two giant galaxy clusters crashing into ...
WebThe relationship is investigated between laminar and turbulent theories of the structure of a collisionless shock wave. For p e ≫ p i, where p i, p e are the ion and electron pressures, a laminar structure of the shock wave may be constructed in terms of the `solitary' wave with thickness of the order of the Debye length. When p i ≳ p e the principal part within … WebThe shock wave travels toward the Sun at the same speed but in the opposite direction as the solar wind, so it appears to stand still with respect to the Earth. Because there are almost no particle-particle collisions, this type of collisionless shock wave is of great interest to space plasma physicists who postulate that similar shocks occur ...
