Syllabus
The solar wind provides a very versatile laboratory to study the physics of interacting plasmas
and the transport and acceleration of particles in space. The acceleration of the hot corona to a
supersonic wind and its interaction with the interstellar neighborhood is a basic example for the
surroundings of stars. Wherever the supersonic solar wind runs into obstacles the formation of
shock waves: at planetary magnetospheres and comets, in the transition from high to low speed
solar wind, at coronal mass ejections, and at the heliospheric boundary. Shock waves are known
as very efficient particle accelerators in the cosmos. A wide variety of them can be studied insitu within the solar system itself. The populations of particles, which are accelerated in
interplanetary space, range from the solar wind proper, via particles from the planetary and
cometary environments to the interstellar gas. In addition, particles accelerated at the sun during
solar flares and cosmic rays from outside the heliosphere have to be considered. We will include
the discussion of the instrumentation necessary to study these phenomena experimentally.
