Abstract:
The work is devoted to the investigation of both the structure of the heliospheric current sheet (HCS) and mechanisms of its formation. Self-consistent hybrid model of the HCS is developed, where ion dynamics has been described in a frame of quasi-adiabatic dynamics, while the electron motion is considered as a fluid one. HCS is found to be a relatively thin multiscale plasma configuration which is embedded inside much thicker plasma sheet. It is shown that HCS can be supported by the current of demagnetized protons on open quasi-adiabatic orbits as well as electron drift currents. The possibility to apply the model results to interpretation of experimental observations is proposed.
