The Sigma Problem of the Crab Pulsar Wind

  title={The Sigma Problem of the Crab Pulsar Wind},
  author={J. Kirk and O. Skjaeraasen},
Flows in which energy is transported predominantly as Poynting flux are thought to occur in pulsars, gamma-ray bursts, and relativistic jets from compact objects. The fluctuating component of the magnetic field in such a flow can in principle be dissipated by magnetic reconnection and used to accelerate the flow. We investigate how rapidly this transition can take place by implementing into a global MHD model that uses a thermodynamic description of the plasma, explicit, physically motivated… Expand

Confinement of the Crab Nebula with tangled magnetic field by its supernova remnant
A pulsar wind is a relativistic outflow dominated by Poynting energy at its base. Based on the standard ideal magnetohydrodynamic (MHD) model of pulsar wind nebulae (PWNe) with the ordered magneticExpand
Superluminal waves in pulsar winds
The energy lost by a rotation-powered pulsar is carried by a relativistic flow containing a mixture of electromagnetic fields and particles. In the inner regions, this is thought to be a magneticallyExpand

Context. Most of the rotational luminosity of a pulsar is carried away by a relativistic magnetised wind in which the matter energy flux is negligible compared to the Poynting flux. However,Expand
Pulsar striped winds
According to magnetohydrodynamic (MHD) models, the rotational energy of a rapidly spinning neutron star is carried away by a relativistic wind and deposited at a large distance, in the nebula,Expand

Waves in pulsar winds
The radio, optical, x-ray and gamma-ray nebulae that surround many pulsars are thought to arise from synchrotron and inverse Compton emission. The energy powering this emission as well as theExpand
Dissipation of the striped pulsar wind
Rapidly rotating neutron stars blow a relativistic, magnetized wind mainly composed of electron-positron pairs. The free expansion of the wind terminates far from the neutron star where a weaklyExpand
Highly magnetized region in pulsar wind nebulae and origin of the Crab gamma-ray flares
The recently discovered gamma-ray flares from the Crab nebula are generally attributed to the magnetic energy release in a highly magnetized region within the nebula. I argue that such a regionExpand
Turbulent Magnetic Relaxation in Pulsar Wind Nebulae
We present a model for magnetic energy dissipation in a pulsar wind nebula. Better understanding of this process is required to assess the likelihood that certain astrophysical transients may beExpand

We study the acceleration of electrons and positrons at an electromagnetically modified, ultrarelativistic shock in the context of pulsar wind nebulae. We simulate the outflow produced by anExpand


An axisymmetric magnetohydrodynamic model for the Crab pulsar wind bubble
We extend Kennel and Coroniti's (1984) spherical magnetohydrodynamic models for the Crab Nebula to include the pinching effect of the toroidal magnetic field. Since the bulk nebular flow is likely toExpand
Acceleration of GRB outflows by Poynting flux dissipation
We study magnetically powered relativistic outflows in which a part of the magnetic energy is dissipated internally by reconnection. For GRB parameters, and assuming that the reconnection speedExpand

Abstract Atraditional problem in pulsar wind physics has been the nature of the pulsar wind.Ontheoretical grounds, the wind is expected to be dominated by Poynting flux associated with the outgoingExpand

Reconnection in a striped pulsar wind
It is generally thought that most of the spin-down power of a pulsar is carried away in an MHD wind dominated by Poynting flux. In the case of an oblique rotator, a significant part of this energyExpand
