White paper on the relevance of the European Solar Telescope (EST) for the French heliophysics
E. Pariat, Q. Noraz, B. Perri +61
The project of the European Solar Telescope aims to provide a state-of-the art infrastructure to study the Sun and its interactions with Earth and the heliosphere. This 4.2m apertu…
Turbulent Heating between 0.2 and 1 au: A Numerical Study
Victor Montagud-Camps, Roland Grappin, Andrea Verdini
The heating of the solar wind is a key to understand its dynamics and acceleration process. The observed radial decrease of proton temperature in the solar wind is slow compared to…
Comparing turbulent cascades and heating vs spectral anisotropy in solar wind via direct simulations
Victor Montagud-Camps, Roland Grappin, Andrea Verdini
In a previous work (MGV18), we showed numerically that the turbulent cascade generated by quasi-2D structures (with wave vectors mostly-perpendicular to the mean magnetic field) is…
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…
3D Anisotropy of Solar Wind Turbulence, Tubes, or Ribbons?
Andrea Verdini, Roland Grappin, Olga Alexandrova +1
We study the anisotropy with respect to the local magnetic field of turbulent magnetic fluctuations at magnetofluid scales in the solar wind. Previous measurements in the fast sola…
Beyond the Maltese cross: geometry of turbulence between 0.2 and 1 AU
Andrea Verdini, Roland Grappin
The spectral anisotropy of turbulent structures has been measured in the solar wind since 1990, relying on the assumption of axisymmetry about the mean magnetic field, B0. However,…
