Properties of Magnetic Switchbacks in the Near-Sun Solar Wind
Samuel T. Badman, Naïs Fargette, Lorenzo Matteini +24
Magnetic switchbacks are fluctuations in the solar wind in which the interplanetary magnetic field sharply deflects away from its background direction so as to create folds in magn…
On the Heating of the Slow Solar-Wind by Imbalanced Alfvén-Wave Turbulence from 0.06 au to 1 au: Parker Solar Probe and Solar Orbiter observations
Sofiane Bourouaine, Jean C. Perez, Benjamin D. G. Chandran +3
In this work we analyze plasma and magnetic field data provided by the Parker Solar Probe (\emph{PSP}) and Solar Orbiter (\emph{SO}) missions to investigate the radial evolution of…
The relation between magnetic switchbacks and turbulence in the inner heliosphere
A. Larosa, C. H. K Chen, J. R. McIntyre +1
We investigate the relation between turbulence and magnetic field switchbacks in the inner heliosphere below 0.5 AU in a distance and scale dependent manner. The analysis is perfor…
Whistler waves generated inside magnetic dips in the young solar wind: observations of the Search-Coil Magnetometer on board Parker Solar Probe
C. Froment, O. V. Agapitov, V. Krasnoselskikh +11
Context. Whistler waves are electromagnetic waves produced by electron-driven instabilities, that in turn can reshape the electron distributions via wave-particle interactions. In…
Parker Solar Probe: Four Years of Discoveries at Solar Cycle Minimum
N. E. Raouafi, L. Matteini, J. Squire +54
Launched on 12 Aug. 2018, NASA's Parker Solar Probe had completed 13 of its scheduled 24 orbits around the Sun by Nov. 2022. The mission's primary science goal is to determine the…
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…
Whistler wave occurrence and the interaction with strahl electrons during the first encounter of Parker Solar Probe
V. K. Jagarlamudi, T. Dudok de Wit, C. Froment +16
We studied the properties and occurrence of narrow band whistler waves and their interaction with strahl electrons observed between 0.17 and 0.26 au during the first encounter of P…
Switchbacks: statistical properties and deviations from alfvénicity
A. Larosa, V. Krasnoselskikh, T. Dudok de Witınst +16
{Parker Solar Probe's first solar encounter has revealed the presence of sudden magnetic field deflections that are called switchbacks and are associated with proton velocity enhan…
Whistler Waves and Electron Properties in the Inner Heliosphere: Helios Observations
Vamsee Krishna Jagarlamudi, Olga Alexandrova, Laura Bercic +4
We present the analysis of narrowband whistler wave signatures observed in the inner heliosphere (0.3-1 au). These signatures are bumps in the spectral density in the 10-200 Hz fre…
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…
Switchbacks in the near-Sun magnetic field: long memory and impact on the turbulence cascade
Thierry Dudok de Wit, Vladimir V. Krasnoselskikh, Stuart D. Bale +14
One of the most striking observations made by Parker Solar Probe during its first solar encounter is the omnipresence of rapid polarity reversals in a magnetic field that is otherw…
