Asteroseismic Signature of a Large Active Region
Emanuele Papini, Laurent Gizon
Axisymmetric magnetic activity on the Sun and Sun-like stars increases the frequencies of the modes of acoustic oscillation. However, it is unclear how a corotating patch of activi…
Turbulence vs. fire hose instabilities: 3-D hybrid expanding box simulations
P. Hellinger, L. Matteini, S. Landi +3
The relationship between a decaying plasma turbulence and proton fire hose instabilities in a slowly expanding plasma is investigated using three-dimensional (3-D) hybrid expanding…
Fast Magnetic Reconnection: Secondary Tearing Instability and Role of the Hall Term
Emanuele Papini, Simone Landi, Luca Del Zanna
Magnetic reconnection provides the primary source for explosive energy release, plasma heating and particle acceleration in many astrophysical environments. The last years witnesse…
Spectral anisotropies and intermittency of plasma turbulence at ion kinetic scales
Simone Landi, Luca Franci, Emanuele Papini +3
By means of three dimensional high-resolution hybrid simulations we study the properties of the magnetic field spectral anisotropies near and beyond ion kinetic scales. By using bo…
Three-dimensional local anisotropy of velocity fluctuations in the solar wind
Andrea Verdini, Roland Grappin, Olga Alexandrova +4
We analyse velocity fluctuations in the solar wind at magneto-fluid scales in two datasets, extracted from Wind data in the period 2005-2015, that are characterised by strong or we…
[Plasma 2020 Decadal] The essential role of multi-point measurements in turbulence investigations: the solar wind beyond single scale and beyond the Taylor Hypothesis
W. H. Matthaeus, R. Bandyopadhyay, M. R. Brown +46
This paper briefly reviews a number of fundamental measurements that need to be made in order to characterize turbulence in space plasmas such as the solar wind. It has long been k…
