One characteristic trait of space plasmas is the multi-scale dynamics resulting from non-
linear transfers and conversions of various forms of energy. Routinely evidenced in a range …

In this review we will focus on a topic of fundamental importance for both astrophysics and
plasma physics, namely the occurrence of large-amplitude low-frequency fluctuations of the …

Solar wind is probably the best laboratory to study turbulence in astrophysical plasmas. In
addition to the presence of magnetic field, the differences with neutral fluid isotropic …

Abstract Parker Solar Probe (PSP) and SolO data are utilized to investigate magnetic field
intermittency in the solar wind (SW). Small-scale intermittency (20− 100 di) is observed to …

In spite of a large number of papers dedicated to the study of MHD turbulence in the solar
wind there are still some simple questions which have never been sufficiently addressed …

The nature of the Elsässer variable z− plays a significant role in the understanding of solar
wind turbulence. The radial spectral evolution of z− observed by the Helios spacecraft …

The parametric instability of two-dimensional Alfvénic turbulence has been studied via direct
numerical simulations of magnetohydrodynamics. A general form for an Alfvénic fluctuation …

The Alfvén wave (AW) is the most common fluctuation present within the solar wind emitted
from the Sun. Whether or not AWs can originate after the collision of an Interplanetary …

The solar wind is a highly turbulent medium, with a high level of field fluctuations throughout
a broad range of scales. These include an inertial range where a turbulent cascade is …
