Conversion Layer Controls the Evolution of Magnetic Deflections Near the Alfven Surface
Dominic Payne, Mojtaba Akhavan-Tafti, Joshua Goodwill +10
We examine the statistics of Alfvenic deflections in both sub-Alfvenic and super-Alfvenic solar wind with particular focus on a common parameter that underlies the definition of sw…
Characterization of the Trans-Alfvénic Region Using Observations from Parker Solar Probe
Subash Adhikari, Riddhi Bandyopadhyay, Joshua Goodwill +14
Close to Earth the solar wind is usually super-Alfvénic, i.e. the speed of the solar wind is much larger than the Alfvén speed. However, in the lower coronal regions, the solar w…
Density Fluctuations in the Solar Wind Driven by Alfvén Wave Parametric Decay
Trevor A. Bowen, Samuel Badman, Petr Hellinger +1
Measurements and simulations of inertial compressive turbulence in the solar wind are characterized by anti-correlated magnetic fluctuations parallel to the mean field and density…
Observed Fluctuation Enhancement and Departure from WKB Theory in Sub-Alfvénic Solar Wind
David Ruffolo, Panisara Thepthong, Peera Pongkitiwanichakul +12
Using Parker Solar Probe data from orbits 8 through 17, we examine fluctuation amplitudes throughout the critical region where the solar wind flow speed approaches and then exceeds…
Effect of Spherical Polarization on the Magnetic Spectrum of the Solar Wind
Corina Dunn, Trevor Bowen, Alfred Mallet +2
Magnetic fluctuations in the solar wind are often observed to maintain constant magnitude of the magnetic field in a manner consistent with spherically-polarized large-amplitude Al…
Evolution and Impact of Switchbacks Throughout the Heliosphere
Alfred Mallet, Chen Shi, Anna Tenerani +23
Magnetic switchbacks are large-amplitude fluctuations in the interplanetary magnetic field, and appear frequently in the near-Sun solar wind explored recently by Parker Solar Probe…
