Abstract Launched on 12 Aug. 2018, NASA's Parker Solar Probe had completed 13 of its
scheduled 24 orbits around the Sun by Nov. 2022. The mission's primary science goal is to …

Solar energetic particles, or SEPs, from suprathermal (few keV) up to relativistic (∼∼ few
GeV) energies are accelerated near the Sun in at least two ways:(1) by magnetic …

This is an overview of the solar modulation of cosmic rays in the heliosphere. It is a broad
topic with numerous intriguing aspects so that a research framework has to be chosen to …

The theory of nearly incompressible magnetohydrodynamics (NI MHD) was developed
largely in the early 1990s, together with an important extension to inhomogeneous flows in …

Energetic particles are accelerated in rich profusion at sites throughout the heliosphere.
They come from solar flares in the low corona, from shock waves driven outward by coronal …

The magnetic field experiment on ACE provides continuous measurements of the local
magnetic field in the interplanetary medium. These measurements are essential in the …

The dissipation range for interplanetary magnetic field fluctuations is formed by those
fluctuations with spatial scales comparable to the gyroradius or ion inertial length of a …

We present a new analysis of the transport of cosmic rays in a turbulent magnetic field that
varies in all three spatial dimensions. The analysis utilizes a numerical simulation that …

Modelling the transport of cosmic rays (CRs) in the heliosphere represents a global
challenge in the field of heliophysics, in that such a study, if it were to be performed from first …

Two new methods for distinguishing two‐dimensional (2D) turbulence from slab turbulence
are applied to Helios magnetometer data. Two‐component models with varying slab and 2D …
