Zusammenfassung/Abstract:
In recent years, the Voyager and IBEX spacecraft have tremendously increased our knowledge about the structure of the outer heliosphere, i.e. the circumsolar space occupied by the solar wind plasma, and the interstellar medium beyond. Their complementary in situ and remote measurements have led to a critical revision of long-standing paradigms and have triggered a new understanding of the outer boundary region of the heliosphere. A corresponding overview will be given along with a discussion of the propagation physics of energetic particles in this heliospheric regime and its significance for our understanding of heliospheric and local interstellar structure as well as of fundamental transport processes.
