Turbulence Upstream and Downstream of Interplanetary Shocks [PDF]
Frontiers in Physics, 2021 The paper reviews the interaction of collisionless interplanetary (IP) shocks with the turbulent solar wind. The coexistence of shocks and turbulence plays an important role in understanding the acceleration of particles via Fermi acceleration mechanisms,

Effect of interplanetary shock waves on turbulence parameters [PDF]
Annales GeophysicaeWe perform an extensive statistical investigation of how interplanetary fast forward shocks affect certain turbulence parameters, namely, the normalised cross-helicity, σc; residual energy, σr; and magnetic helicity, σm.

Interplanetary and interstellar plasma turbulence [PDF]
Plasma Physics and Controlled Fusion, 2007 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.

Shock waves propagation in the turbulent interplanetary plasma [PDF]
Advances in Space Research, 1996 AbstractEffect of turbulence on interplanetary shock waves propagation is considered. It is shown that background turbulence results in the additional shock wave deceleration which may be comparable with the deceleration due to plasma sweeping. The turbulent deceleration is connected with the energy losses due to the strong turbulence amplification ...

The Astrophysical Journal, 2023 In this work, we extend Leighton’s diffusion model describing the turbulent mixing of magnetic footpoints on the solar wind source surface. The present Lagrangian stochastic model is based on the spherical Ornstein–Uhlenbeck process with drift that is ...

Relationship of Transport Coefficients with Statistical Quantities of Charged Particles
The Astrophysical Journal, 2023 In previous studies, a general spatial transport equation was derived from the Fokker–Planck equation. The latter equation contains an infinite number of spatial derivative terms T _n = κ _nz ∂ ^n F /∂ z ^n with n = 1, 2, 3, ⋯ .

Structure of the Turbulent Interplanetary Magnetic Field [PDF]
The Astrophysical Journal, 2006 We show that two widely used but apparently different models of the turbulent interplanetary magnetic field are closely related. One of these is the so-called quasi-static turbulence model, in which interplanetary magnetic field fluctuations are generated at a source surface near the Sun by random transverse plasma motions (such as supergranulation at ...

Cosmic ray fluctuations and MHD waves in the solar wind
Solar-Terrestrial Physics, 2023 During large-scale solar wind disturbances, variations in galactic cosmic rays with periods from several minutes to 2–3 hours, which are called cosmic ray fluctuations in the scientific literature, often occur.

Kinematic models of the interplanetary magnetic field [PDF]
Annales Geophysicae, 2019 Current knowledge on the description of the interplanetary magnetic field is reviewed with an emphasis on the kinematic approach as well as the analytic expression.
