Abstract:
In the heliospheric boundary region matter and energy are extensively transported and/or converted between the heliosphere and the local interstellar space. This region has been explored in-situ by Voyager spacecraft in this century. Voyager spacecraft revealed a lot of features of the two important discontinuities, termination shock and heliopause, as well as unexpected properties of high energy particles in the boundary region. Some of the features have been still not well understood. We first review our full particle-in-cell simulation studies to discuss kinetic properties of the two discontinuities. Then, we further discuss our recent work on the effect of global structure of the heliosphere in the cosmic ray invasion process into the heliosphere.
