ASYMPTOTIC STRUCTURE OF POYNTING-DOMINATED JETS
ASYMPTOTIC STRUCTURE OF POYNTING-DOMINATED JETS
In relativistic, Poynting-dominated outflows, acceleration and collimation are intimately connected. An important point is that the Lorentz force is nearly compensated by the electric force; therefore the acceleration zone spans a large range of scales. We derived the asymptotic equations describing relativistic, axisymmetric magnetohydrodynamic flows far beyond the light cylinder. …
