Transport of solar electrons in the turbulent interplanetary magnetic field

Physics of Plasmas, 2016
The turbulent transport of solar energetic electrons in the interplanetary magnetic field is investigated by means of a test-particle Monte-Carlo simulation. The magnetic fields are modeled as a combination of the Parker field and a turbulent component.

Turbulent Generation of Outward-Traveling Interplanetary Alfvénic Fluctuations

Physical Review Letters, 1983
Additional evidence is presented for the dynamic alignment of the fluctuating plasma fluid velocity and the fluctuating magnetic field in two-dimensional MHD turbulence. The evidence is seen as indicating that the interplanetary fluctuations need not represent time-asymptotic states. Rather, it is contended that interplanetary Alfvenic fluctuations are

A power spectral analysis of turbulence associated with interplanetary shock waves

AIP Conference Proceedings, 2013
We calculate the power spectra densities of magnetic field fluctuations associated with interplanetary shock waves at 1AU, utilizing in-situ magnetic field measurements from spacecraft ACE and Wind. We derive related quantities both upstream and downstream of a shock as a function of time/distance away from the shock passage.

Hydromagnetic Waves, Turbulence, and Collisionless Processes in the Interplanetary Medium

1983
The solar wind does not flow quietly. It seethes and undulates, fluctuating on time scales that range from the solar rotation period down to fractions of milliseconds. Most of the power in interplanetary waves and turbulence lies at hydromagnetic scales.

The turbulent evolution of an interplanetary magnetic cloud in the expanding solar wind

Interplanetary coronal mass ejections often carry large-scale magnetic clouds, which display internal substructures and small-scale fluctuations. These complex multi-scale clouds represent the main drivers of geomagnetic storms at Earth, and the amplitude, coherence and variability of their magnetic field all contribute to their geoeffectivity.We ...
