Relativistic magnetohydrodynamics

چکیده
The lowest-order description of a magnetized plasma is given by magnetohydrodynamics (MHD). However, many astrophysical plasmas (as well as some laboratory plasmas) are relativistic, in that either the thermal speed or the fluid flow speed approaches the speed of light, and conventional MHD is not consistent with special relativity. Beginning with exact laws of motion, this work derives a generalization of MHD that is Lorentz covariant and therefore applicable to relativistic plasma. The resulting closed set of fluid equations is then seen to reduce to conventional MHD in the nonrelativistic limit. keywords: stars: atmospheres, galaxies: jets, methods: analytical, physical data and processes, relativistic plasmas

The exact solution of the Riemann problem in relativistic magnetohydrodynamics
We discuss the procedure for the exact solution of the Riemann problem in special relativistic magnetohydrodynamics (MHD). We consider both initial states leading to a set of only three waves analogous to the ones in relativistic hydrodynamics, as well as generic initial states leading to the full set of seven MHD waves. Because of its generality, the solution presented here could serve as an i...

Primitive Variable Solvers for Conservative General Relativistic Magnetohydrodynamics
Conservative numerical schemes for general relativistic magnetohydrodynamics (GRMHD) require a method for transforming between “conserved” variables such as momentum and energy density and “primitive” variables such as restmass density, internal energy, and components of the four-velocity. The forward transformation (primitive to conserved) has a closed-form solution, but the inverse transforma...
متن کاملMagnetized Tori of Black Holes
The dynamics of accretion disks around galactic and extragalactic black holes may be influenced by their magnetic field. In this paper we generalize the fully relativistic theory of stationary axisymmetric tori in Kerr metric of Abramowicz et al.(1978) by including strong toroidal magnetic field. This development is particularly important for the general relativistic computational magnetohydrod...

The accurate modelling of astrophysical scenarios involving compact objects and magnetic fields, such as the collapse of rotating magnetized stars to black holes or the phenomenology of γ-ray bursts, requires the solution of the Einstein equations together with those of general-relativistic magnetohydrodynamics. We present a new numerical code developed to solve the full set of general-relativi...
