Turbulence transport throughout the heliosphere

Multifractal Turbulence in the Heliosphere

Mechansims for Latitudinal Transport of Energetic Particles in the Heliosphere

Energetic particles in the heliosphere, from relatively low-energy particles which are accelerated in Corotating Interaction Regions (CIRs) to galactic cosmic rays, are observed to propagate relatively easily in heliographic latitude. Two mechanisms for this transport appear possible: cross-field diffusion, or, in a recent model for the heliospheric magnetic field, by direct magnetic connection...

Transport and Turbulence

This report is a summary of discussions held in the transport and turbulence breakout subgroups of the Magnetic Confinement Concepts Working Group (which met in the mornings) and the Plasma Sciences Working Group (which met in the afternoons). It was the judgement of the convenors of these groups, that a combined report was appropriate considering the overlap in subject matter and membership of...

A Simple Model for Reflection-Driven Spectral Evolution of Turbulence in the Corona and Inner Heliosphere

Dissipation of turbulence is generally considered as a prime candidate for the heating and acceleration of solar wind from the corona throughout the heliosphere, due to radially evolving dissipation processes and/or cascading of energy to dissipation scales. In order to model the latter consistently, we must consider the evolution of cross-helicity when modeling the strength of the cascade, as ...

The Heliosphere in Time

Because of the dynamic nature of the interstellar medium, the Sun should have encountered a variety of different interstellar environments in its lifetime. As the solar wind interacts with the surrounding interstellar medium to form a heliosphere, different helio-sphere shapes, sizes, and particle contents result from the different environments. Some of the large possible interstellar parameter...
