We present a statistical analysis on the variability of incompressible energy cascade rate in solar wind around Mars, making use an exact relation for fully developed turbulence and more than five years Mars Atmosphere Volatile EvolutioN (MAVEN) observations. Using magnetic field plasma data, we compute magnetohydrodynamics (MHD) scales pristine wind. From our results, conclude that decreases a...

We show that the backreaction of left-handed neutrinos out equilibrium on matter sector induces an electric current proportional to a magnetic field even without chiral imbalance for electrons in core-collapse supernovae. derive transport coefficient this effect based recently formulated radiation theory neutrinos. This generates strong via so-called plasma instability, which could provide new ...

The dynamics of accretion discs around galactic and extragalactic black holes may be influenced by their magnetic field. In this paper we generalise the fully relativistic theory of stationary axisymmetric tori in Kerr metric of Abramowicz et al.(1978) by including strong toroidal magnetic field and construct analytic solutions for barotropic tori with constant angular momentum. This developmen...

We have developed a new, quasi-Lagrangian approach for numerical modeling of magnetohydrodynamics in low to moderate b plasmas such as the solar corona. We introduce the concept of a ‘‘fluxon’’, a discretized field line. Fluxon models represent the magnetic field as a skeleton of such discrete field lines, and interpolate field values from the geometry of the skeleton where needed, reversing th...

Hot, diffuse, relativistic plasmas such as sub-Eddington black hole accretion flows are expected to be collisionless, yet are commonly modeled as a fluid using ideal general relativistic magnetohydrodynamics (GRMHD). Dissipative effects such as heat conduction and viscosity can be important in a collisionless plasma and will potentially alter the dynamics and radiative properties of the flow fr...

On electron kinetic scales, ions and electrons decouple, velocity shear on inertial length ∼de can trigger electromagnetic (EM) Kelvin–Helmholtz instability (EKHI). In this paper, we present an analytic study of EM EKHI in inviscid collisionless plasma with a step-function flow. We show that incompressible plasma, the ideal frozen-in condition E+ve×B/c=0 must be broken for to occur. flow, is re...

Article history: Received 2 November 2014 Accepted 5 December 2014 Available online 9 December 2014 Communicated by F. Porcelli A version of extended magnetohydrodynamics (MHD) that incorporates electron inertia is obtained by constructing an action principle. Unlike MHD which freezes in magnetic flux, the present theory freezes in an alternative flux related to the electron canonical momentum....

The properties of collisionless shocks, like the density jump, are usually derived from magnetohydrodynamics (MHD), where isotropic pressures assumed. Yet, in a plasma, an external magnetic field can sustain stable anisotropy. In \cite{BretJPP2018}, we devised model for kinetic history plasma through shock front, allowing to self-consistently compute downstream anisotropy, hence terms upstream ...
