@article{Hazeltine2002FluidDO, title={Fluid Description of Relativistic, Magnetized Plasma}, author={R. D. Hazeltine and Swadesh Mitter Mahajan}, journal={The Astrophysical Journal}, year={2002}, volume={567}, pages={1262-1271} }

Many astrophysical plasmas and some laboratory plasmas are relativistic: either the thermal speed or the local flow speed (in a convenient frame) approaches the speed of light. Many such plasmas are also magnetized, in the sense that the thermal Larmor radius is smaller than gradient scale lengths. Relativistic MHD, conventionally used to describe such systems, requires the collision time to be shorter than any other timescale in the system. On this assumption, it uses the thermodynamic… Expand
