Turbulence in the interstellar medium [PDF]
, 2014 Turbulence is ubiquitous in the insterstellar medium and plays a major role in several processes such as the formation of dense structures and stars, the stability of molecular clouds, the amplification of magnetic fields, and the re-acceleration and ...

The influence of a mean magnetic field on three-dimensional magnetohydrodynamic turbulence [PDF]
, 1994 Building on results from two-dimensional magnetohydrodynamic (MHD) turbulence (Shebalin, Matthaeus & Montgomery 1983), the development of anisotropic states from initially isotropic ones is investigated numerically for fully three-dimensional ...

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 ...

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 ...

Electron and proton heating by solar wind turbulence [PDF]
, 2009 Previous formulations of heating and transport associated with strong magnetohydrodynamic (MHD) turbulence are generalized to incorporate separate internal energy equations for electrons and protons. Electron heat conduction is included.

Transport of cross helicity and radial evolution of alfvenicity in the solar wind [PDF]
, 2004 A transport theory including cross helicity, magnetohydrodynamic(MHD) turbulence, and driving by shear and pickup ions, is applied to the radial evolution of the solar wind.

Interpretation of Flat Energy Spectra Upstream of Fast Interplanetary Shocks
The Astrophysical Journal, 2023 Interplanetary shocks are large-scale heliospheric structures often caused by eruptive phenomena at the Sun, and represent one of the main sources of energetic particles.
