| Session Description |
Cosmophysical plasma jets can be defined as localized non-relativistic fast streams of dense plasma whose kinetic energy density exceeds substantially the energy density of ambient plasma and magnetic field. The jets are revealed in various space domains: jets in the solar corona, erupting filaments from the chromosphere to interplanetary medium, high-beta jets in the magnetosheath and reconnection exhausts in the magnetotail. A number of mechanisms were proposed for generation of the jets: magnetic reconnection, stochastic generation in a region of not-fully developed plasma turbulence, and induced by interaction of MHD discontinuities with boundary layers. Jets are considered as an important driver of plasma transport and plasma penetration across the boundary layers by means of such mechanisms as impulsive penetration, reconnection and kinetic effect of ions with a finite gyroradius. The Session encourages presentations of observational and modeling results related to jet generation, propagation and interaction with boundary layers. |
