Characterization of the Transmission and Generation of Turbulence at Interplanetary Shocks
The Astrophysical JournalWe study the transmission and characteristics of turbulent magnetohydrodynamic (MHD) fluctuations from upstream to downstream regions of interplanetary (IP) shocks using the linear mode decomposition (LMD) technique of G. P. Zank et al.

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

Particle acceleration at shocks and magnetic turbulence in the interplanetary space
, 2019 Dottorato Ricerca in Scienze e Tecnologie Fisiche, Chimiche e dei Materiali. Ciclo XXXIThe solar wind is a supersonic and super-alfvenic flow of plasma that propagates in space up to the Earth and throughout the heliosphere reaching speeds of about 400

Interplanetary MHD turbulence: A wavelet approach
, 1997 Using solar wind data recorded by the Helios-2 spacecraft at 0.3 AU we analyse MHD turbulence by means of continuous wavelet transform. This new technique, differently from FFT technique, provides a good spatial and temporal resolution.

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 ...

MHD Turbulence in the Solar Wind and Interplanetary Dynamo Effects [PDF]
Symposium - International Astronomical Union, 1993 From the fluctuations of the velocity and magnetic field observed in different kinds of solar wind the fluctuating electric fields are derived, and their power spectra are constructed and analysed. The mean electromotive force ɛ generated by the turbulent motions depends upon the nature of the fluctuations.

Three-dimensional spatial structures of solar wind turbulence from 10 000-km to 100-km scales [PDF]
, 2011 Using the four Cluster spacecraft, we have determined the three-dimensional wave-vector spectra of fluctuating magnetic fields in the solar wind. Three different solar wind intervals of Cluster data are investigated for this purpose, representing ...

von Karman Correlation Similarity of the Turbulent Interplanetary Magnetic Field
The Astrophysical Journal Letters, 2021 Abstract A major development underlying much of hydrodynamic turbulence theory is the similarity decay hypothesis due to von Karman and Howarth here extended empirically to magnetic field fluctuations in the solar wind. In similarity decay the second-order correlation experiences a continuous transformation based on a universal ...
