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 ...

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.

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.

The Astrophysical Journal, 2023 The discovery of very prominent magnetic kinks/switchbacks in the solar wind within 0.3 au has become a scientific highlight of the Parker Solar Probe (PSP) mission. This discovery points at the promising impact of small-scale solar activity on the inner

On the probability distribution function of small scale interplanetary magnetic field fluctuations [PDF]
, 2004 In spite of a large number of papers dedicated to study MHD turbulence in the solar wind there are still some simple questions which have never been sufficiently addressed like: a)do we really know how the magnetic field vector orientation fluctuates in ...
