The Second Quadratic Invariant of Astrophysical Gyrokinetics
Benjamin D. G. Chandran, Alfred Mallet, Romain Meyrand
The paper identifies a previously unknown quadratic invariant, called gyrokinetic helicity, in astrophysical gyrokinetics and derives its forms across several reduced plasma models…
Intermittent, Reflection-Driven, Strong Imbalanced MHD Turbulence
B. D. G. Chandran, N. Sioulas, S. Bale +4
We develop a phenomenological model of strong imbalanced magnetohydrodynamic (MHD) turbulence that accounts for intermittency and the reflection of Alfven waves by spatial variatio…
Generalized Expanding-Box Formulations of Reduced Magnetohydrodynamics in the Solar Wind
Vincent David, Benjamin D. G. Chandran, Romain Meyrand +2
We derive a set of simplified equations that can be used for numerical studies of reduced magnetohydrodynamic turbulence within a small patch of the radially expanding solar wind.…
