An Extended and Fragmented Alfvén Zone in the Young Solar Wind
Rohit Chhiber, William H. Matthaeus, Arcadi V. Usmanov +2
Motivated by theoretical, numerical, and observational evidence, we explore the possibility that the critical transition between sub-Alfvénic flow and super-Alfvénic flow in the so…
Magnetic Field Line Random Walk and Solar Energetic Particle Path Lengths: Stochastic Theory and PSP/ISoIS Observation
R. Chhiber, W. H. Matthaeus, C. M. S. Cohen +21
Context:In 2020 May-June, six solar energetic ion events were observed by the Parker Solar Probe/ISoIS instrument suite at 0.35 AU from the Sun. From standard velocity-dispersion a…
Contextual Predictions for Parker Solar Probe II: Turbulence Properties and Taylor Hypothesis
Rohit Chhiber, Arcadi V. Usmanov, William H. Matthaeus +2
The Parker Solar Probe (PSP) primary mission extends seven years and consists of 24 orbits of the Sun with descending perihelia culminating in a closest approach of ($\sim 9.8~R_\o…
Contextual Predictions for Parker Solar Probe I: Critical Surfaces and Regions
Rohit Chhiber, Arcadi V. Usmanov, William H. Matthaeus +1
The solar corona and young solar wind may be characterized by critical surfaces -- the sonic, Alfvén, and first plasma- unity surfaces -- that demarcate regions where the solar…
The Origin of Non-Maxwellian Solar Wind Electron Velocity Distribution Function: Connection to Nanoflares in the Solar Corona
H. Che, M. Goldstein
The formation of the observed core-halo feature in the solar wind electron velocity distribution function is a long-time puzzle. In this letter based on the current knowledge of na…
Relaxation Processes in Solar Wind Turbulence
S. Servidio, C. Gurgiolo, V. Carbone +1
Based on global conservation principles, magnetohydrodynamic (MHD) relaxation theory predicts the existence of several equilibria, such as the Taylor state or global dynamic alignm…
