The Effects of Non-Equilibrium Velocity Distributions on Alfvén Ion-Cyclotron Waves in the Solar Wind
Jada Walters, Kristopher G. Klein, Emily Lichko +3
In this work, we investigate how the complex structure found in solar wind proton velocity distribution functions (VDFs), rather than the commonly assumed two-component bi-Maxwelli…
Ion-Driven Instabilities in the Inner Heliosphere II: Classification and Multi-Dimensional Mapping
Mihailo M. Martinovic, Kristopher G. Klein
Linear theory is a well developed framework for characterizing instabilities in weakly collisional plasmas, such as the solar wind. In the previous instalment of this series, we an…
Quantifying the Energy Budget in the Solar Wind from 13.3-100 Solar Radii
J. S. Halekas, S. D. Bale, M. Berthomier +10
A variety of energy sources, ranging from dynamic processes like magnetic reconnection and waves to quasi-steady terms like the plasma pressure, may contribute to the acceleration…
How Alfvén waves energize the solar wind: heat vs work
Jean C. Perez, Benjamin D. G. Chandran, Kristopher G. Klein +1
A growing body of evidence suggests that the solar wind is powered to a large extent by an Alfvén-wave (AW) energy flux. AWs energize the solar wind via two mechanisms: heating and…
Multiscale Solar Wind Turbulence Properties inside and near Switchbacks measured by Parker Solar Probe
Mihailo M. Martinović, Kristopher G. Klein, Jia Huang +9
Parker Solar Probe (PSP) routinely observes magnetic field deflections in the solar wind at distances less than 0.3 au from the Sun. These deflections are related to structures com…
Inferred Linear Stability of Parker Solar Probe Observations using One- and Two-Component Proton Distributions
K. G. Klein, J. L. Verniero, B. Alterman +12
The hot and diffuse nature of the Sun's extended atmosphere allows it to persist in non-equilibrium states for long enough that wave-particle instabilities can arise and modify the…
