Seminar Abstract:

Global hybrid modelling is a way to study kinetic interactions of unmagnetized and weakly magnetized Solar System bodies with the solar wind. In a quasi-neutral hybrid code ions are treated as particle clouds moving under the Lorentz force and coupled self-consistently with electric and magnetic fields and electrons are a charge-neutralizing, massless fluid.

HYB is the hybrid simulation platform developed and used at the Finnish Meteorological Institute for more than a decade already. The HYB platform includes several global models for plasma interactions of Solar System planets and moons and, for example, local models for reconnection and magnetic anomalies.

In this presentation we discuss some of our recent simulation studies including hemispheric asymmetries of the Venusian induced magnetosphere, ion escape from Venus, solar energetic particles at Mars and the solar wind interaction with a lunar mini-magnetosphere.
