A high-sigma model of pulsar wind nebulae
A high-sigma model of pulsar wind nebulae
Pulsars and central engines of long gamma-ray bursts – collapsars – may produce highly magnetized (Poynting-flux-dominated) outflows expanding in dense surroundings (interstellar medium or stellar material). For certain injection conditions, the magnetic flux of the wind cannot be accommodated within the cavity. In this case, ideal (non-dissipative) magnetohydrodynamics models, similar …
