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…
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…
Turbulence characteristics of switchbacks and non-switchbacks intervals observed by \emph{Parker Solar Probe}
Sofiane Bourouaine, Jean C. Perez, Kristopher C. Klein +5
We use \emph{Parker Solar Probe} (\emph{PSP}) in-situ measurements to analyze the characteristics of solar wind turbulence during the first solar encounter covering radial distance…
The Solar Orbiter Science Activity Plan: translating solar and heliospheric physics questions into action
I. Zouganelis, A. De Groof, A. P. Walsh +182
Solar Orbiter is the first space mission observing the solar plasma both in situ and remotely, from a close distance, in and out of the ecliptic. The ultimate goal is to understand…
Proton Temperature Anisotropy Variations in Inner Heliosphere Estimated with First Parker Solar Probe Observations
Jia Huang, Justin C. Kasper, Daniel Vech +27
We report proton temperature anisotropy variations in the inner heliosphere with Parker Solar Probe (PSP) observations. Using a linear fitting method, we derive proton temperature…
Linear Stability in the Inner Heliosphere: Helios Reëvaluated
Kristopher G. Klein, Mihailo Martinovic, David Stansby +1
Wave-particle instabilities driven by departures from local thermodynamic equilibrium have been conjectured to play a role in governing solar wind dynamics. We calculate the statis…
