Correlations at large scales and the onset of turbulence in the fast solar wind

Robert T. Wicks, D. Aaron Roberts, Alfred Mallet +3

We show that the scaling of structure functions of magnetic and velocity fields in a mostly highly Alfvénic fast solar wind stream depends strongly on the joint distribution of the…

Collisional Thermalization of Hydrogen and Helium in Solar Wind Plasma

Bennett A. Maruca, Stuart D. Bale, Luca Sorriso-Valvo +2

In situ observations of the solar wind frequently show the temperature of -particles (fully ionized helium), , to significantly differ from that of protons (ionized hydroge…

Nonlinear evolution of the magnetized Kelvin-Helmholtz instability: from fluid to kinetic modeling

P. Henri, S. S. Cerri, F. Califano +11

The nonlinear evolution of collisionless plasmas is typically a multi-scale process where the energy is injected at large, fluid scales and dissipated at small, kinetic scales. Acc…

A Parallel-Propagating Alfvénic Ion-Beam Instability in the High-Beta Solar Wind

Daniel Verscharen, Sofiane Bourouaine, Benjamin D. G. Chandran +1

We investigate the conditions under which parallel-propagating Alfvén/ion-cyclotron waves are driven unstable by an isotropic () population of alpha p…

Self-Consistent Ion Cyclotron Anisotropy-Beta Relation for Solar Wind Protons

Philip A. Isenberg, Bennett A. Maruca, Justin C. Kasper

We derive a set of self-consistent marginally stable states for a system of ion-cyclotron waves propagating parallel to the large-scale magnetic field through a homogeneous proton-…

On the Cause of Supra-Arcade Downflows in Solar Flares

P. A. Cassak, J. F. Drake, J. T. Gosling +3

A model of supra-arcade downflows (SADs), dark low density regions also known as tadpoles that propagate sunward during solar flares, is presented. It is argued that the regions of…

The Nature of Subproton Scale Turbulence in the Solar Wind

C. H. K. Chen, S. Boldyrev, Q. Xia +1

The nature of subproton scale fluctuations in the solar wind is an open question, partly because two similar types of electromagnetic turbulence can occur: kinetic Alfven turbulenc…

Residual Energy Spectrum of Solar Wind Turbulence

C. H. K. Chen, S. D. Bale, C. S. Salem +1

It has long been known that the energy in velocity and magnetic field fluctuations in the solar wind is not in equipartition. In this paper, we present an analysis of 5 years of Wi…

The dynamic quasiperpendicular shock: Cluster discoveries

V. Krasnoselskikh, M. Balikhin, S. N. Walker +9

The physics of collisionless shocks is a very broad topic which has been studied for more than five decades. However, there are a number of important issues which remain unresolved…
