Understanding Non-Gaussian Chorus Wave Statistics via the Benjamin-Feir Index
D. J. Ratliff, O. Allanson, D. Rasinskaite +4
We derive an extended wave action model for equatorial chorus waves, identifying a wave activity index (a version of the Benjamin-Feir index, BFI) which indicates non-Gaussian freq…
Inertial-Range Energy Transfer Free from Isotropic Assumption in Turbulent Space Plasma
Zhuoran Gao, Yan Yang, Francesco Pecora +5
The idea of an energy cascade in the inertial range is often invoked in turbulent space plasmas to estimate the energy dissipation rate. Laws governing the behavior of third-order…
Secondary Electron-Only Reconnection Driven by Large Scale Ion-Coupled Reconnection and Electron Kelvin-Helmholtz Instabilities in Hybrid Simulations of Solar Wind Turbulence
Joaquín Espinoza-Troni, Giuseppe Arrò, Francesco Califano +2
Electron-only reconnection (EREC) is a magnetic reconnection regime occurring within subion-scale current sheets (CSs), exhibiting only electron jets, without any ion outflows. ERE…
Differentiating the acceleration mechanisms in the slow and Alfvénic slow solar wind
Yeimy J. Rivera, Samuel T. Badman, J. L. Verniero +18
In the corona, plasma is accelerated to hundreds of kilometers per second, and heated to temperatures hundreds of times hotter than the Sun's surface, before it escapes to form the…
In situ observations of large amplitude Alfvén waves heating and accelerating the solar wind
Yeimy J. Rivera, Samuel T. Badman, Michael L. Stevens +16
After leaving the Sun's corona, the solar wind continues to accelerate and cools, but more slowly than expected for a freely expanding adiabatic gas. We use in situ measurements fr…
Turbulent Energy Conversion Associated with Kinetic Microinstabilities in Earth's Magnetosheath
Harry C. Lewis, Julia E. Stawarz, Lorenzo Matteini +6
Plasma in the terrestrial magnetosheath is characterised by very weak particle-particle collisions, so kinetic microinstabilities are thought to be responsible for regulating the t…
