Observations of Turbulence and Particle Transport at Interplanetary Shocks: Transition of Transport Regimes [PDF]
Astrophysical JournalThe transport of energetic particles is intimately related to the properties of plasma turbulence, a ubiquitous dynamic process that transfers energy across a broad range of spatial and temporal scales.

Interplanetary and interstellar plasma turbulence [PDF]
Plasma Physics and Controlled Fusion, 2006 Theoretical approaches to low-frequency magnetized turbulence in collisionless and weakly collisional astrophysical plasmas are reviewed. The proper starting point for an analytical description of these plasmas is kinetic theory, not fluid equations. The anisotropy of the turbulence is used to systematically derive a series of reduced analytical models.

Turbulence, Intermittency, and Cross-Scale Energy Transfer in an Interplanetary Coronal Mass Ejection [PDF]
Solar Physics, 2023 Solar wind measurements carried out by NASA’s Wind spacecraft before, during, and after the passing of an interplanetary coronal mass ejection (ICME), detected on 12 – 14 September 2014, have been used in order to examine several properties of ...

Non-Gaussianity and cross-scale coupling in interplanetary magnetic field turbulence during a rope–rope magnetic reconnection event [PDF]
, 2018 . In a recent paper ( Chian et al. , 2016 ) it was shown that magnetic reconnection at the interface region between two magnetic flux ropes is responsible for the genesis of interplanetary intermittent turbulence.

FEATURES OF LONG PERIOD VARIATIONS OF GALACTIC COSMIC RAY INTENSITY IN RELATIONS WITH THE TURBULENCE OF THE INTERPLANETARY MAGNETIC FIELD in 1968 - 2014 [PDF]
, 2016 Data of super neutron monitors, Bx, By, Bz components of the interplanetary magnetic field (IMF) a have been used to study a relation of the long-period variations of the galactic cosmic ray (GCR) intensity with IMF turbulence for the period of 1968-2014.

Interplay of Large-scale Drift and Turbulence in the Heliospheric Propagation of Solar Energetic Particles [PDF]
The Astrophysical JournalThe gradient and curvature of the Parker spiral interplanetary magnetic field give rise to curvature and gradient guiding-center drifts on cosmic rays (CRs). The plasma turbulence present in interplanetary space is thought to suppress the drifts; however,

Rigidity Dependence of the Long-Term Variations of Galactic Cosmic-Ray Intensity in Relation to the Interplanetary Magnetic-Field Turbulence: 1968 – 2002 [PDF]
, 2014 We studied the relationship between the power-law exponent γ on the rigidity R of the spectrum of galactic cosmic-ray (GCR) intensity variation (δD(R)/D(R)∝R−γ) and the exponents νy and νz of the power spectral density (PSD) of the By and Bz components ...

Decay of Solar Wind Turbulence behind Interplanetary Shocks
The Astrophysical Journal, 2017 Abstract We investigate the decay of magnetic and kinetic energies behind IP shocks with motivation to find a relaxation time when downstream turbulence reaches a usual solar wind value. We start with a case study that introduces computation techniques and quantifies a contribution of kinetic fluctuations to the general energy balance ...
