Embedded coherent structures from MHD to sub-ion scales in turbulent solar wind at 0.17 au
Alexander Vinogradov, Olga Alexandrova, Pascal Démoulin +6
We study intermittent coherent structures in solar wind magnetic turbulence from MHD to kinetic plasma scales using Parker Solar Probe data during its first perihelion (at 0.17 au)…
Spectrum of kinetic plasma turbulence at 0.3-0.9 astronomical units from the Sun
Olga Alexandrova, Vamsee Krishna Jagarlamudi, Petr Hellinger +3
We investigate spectral properties of turbulence in the solar wind that is a weakly collisional astrophysical plasma, accessible to in-situ observations. Using the Helios search co…
Kinetic turbulence in space plasmas observed in the near-Earth and near-Sun solar wind
Olga Alexandrova, Vamsee Krishna Jagarlamudi, Claudia Rossi +4
Turbulence develops in any stressed flow when the scales of the forcing are much larger than those of the dissipation. In neutral fluids, it consists of chaotic motions in physical…
Compressive Coherent Structures at Ion Scales in the Slow Solar Wind
D. Perrone, O. Alexandrova, A. Mangeney +5
We present a study of magnetic field fluctuations, in a slow solar wind stream, close to ion scales, where an increase of the level of magnetic compressibility is observed. Here, t…
Whistler mode waves and the electron heat flux in the solar wind: Cluster observations
Catherine Lacombe, Olga Alexandrova, Lorenzo Matteini +5
The nature of the magnetic field fluctuations in the solar wind between the ion and electron scales is still under debate. Using the Cluster/STAFF instrument, we make a survey of t…
Vlasov-Poisson simulations of electrostatic parametric instability for localized Langmuir wave packets in the solar wind
Pierre Henri, Francesco Califano, Carine Briand +1
Recent observation of large amplitude Langmuir waveforms during a Type III event in the solar wind have been interpreted as the signature of the electrostatic decay of beam-driven…
