Fig. 5: The modeled electromagnetic field and particle profiles of the nested cavities.
From: Self-consistent kinetic model of nested electron- and ion-scale magnetic cavities in space plasmas
The horizontal axis represents the distance from the cavity center in the logarithmic scale, also normalized by thermal electron and proton gyroradii. Panels a–g show the radial profiles of the magnetic field, electric current, plasma density, electron parallel and perpendicular temperatures, proton temperature, proton and magnetic pressure, and the diagonal terms of the electron pressure tensor. Panel h shows the distributions of the radial electric field, which according to the generalized Ohm’s law can be divided into the convection, Hall, and electron pressure divergence terms. Panels i and j show the proton and electron bulk velocities in the azimuthal direction (together with their E × B and diamagnetic components), respectively. Panel k shows the electron bulk velocity inferred from ref. 16 in direct comparison with panel j.
