Sliding Contacts in Planetary Magnetospheres

摘要: In the planetary magnetospheres there are specific places connected with velocity breakdown, reconnection, and dynamo processes. Here we pay attention to sliding layers. Sliding layers formed in ionosphere, on separatrix surfaces, at magnetopauses boundaries of stellar astrospheres, Alfven radius equatorial magnetosphere rapidly rotating strongly magnetized giant planets. Although contacts usually occur thin local layers, their influence global structure surrounding space is very great. Therefore, they associated non-local processes that play a key role large scale. There can be an exchange between different forms energy, generation strong field-aligned currents emissions, amplification magnetic fields. Depending conditions planet/exoplanet flow plasma passing it, numbers configurations appear. Some regions auroras possible radio emissions. The search for emissions current task detection exoplanets.
