   Sammanfattning : The Poisson-Boltzmann equation is the standard tool for studying the electrostatic interactions in electrolyte solutions, although it neglects e.g. the ion size and ion-ion correlations. Even experimentally observed specific ion effects cannot be explained in a view of this approximation. LÄS MER

   Sammanfattning : The streaming plasma in the solar wind is a never ending source of energy, plasma, and momentum for planetary magnetospheres, and it continuously drives large-scale plasma convection systems in our magnetosphere and over our polar ionosphere. This coupling between the solar wind and the magnetosphere is primarily explained by two different processes: magnetic reconnection at high latitudes, which interconnects the interplanetary magnetic field (IMF) with the planetary dipole field, and low-latitude dynamos such as viscous interaction, where the streaming plasma in the solar wind may trigger waves and instabilities at the flanks of the magnetosphere, and thereby allow solar wind plasma to enter into the system.
