Rates of reconnection in pulsar winds
نویسنده
چکیده
Using the formulation of relativistic reconnection by Lyutikov & Uzdensky (2002) we estimate the upper possible rates of reconnection in pulsar winds using Bohm prescription for resistivity. We find that the velocity of plasma inflow into the reconnection layer may be relativistic, of the order of the speed of light in the plasma rest-frame. This in principle may allow efficient dissipation of the magnetic field energy in the wind and/or destruction of the toroidal magnetic flux. The efficiency of reconnection realized in pulsar winds remains an open question: it should depend both on the microphysical properties of plasma and on the three-dimensional structure of the reconnection flow.

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 energy can be considered to be in a low-frequency wave, consisting of stripes of toroidal magnetic field of alternating polarity, propagating in a region around the equatorial plane. Magnetic reconnection in...
متن کاملReconnection in pulsar winds
The spin-down power of a pulsar is thought to be carried away in an MHD wind in which, at least close to the star, the energy transport is dominated by Poynting flux. The pulsar drives a low-frequency wave in this wind, consisting of stripes of toroidal magnetic field of alternating polarity, propagating in a region around the equatorial plane. The current implied by this configuration falls of...
متن کاملMagnetic reconnection at the termination shock in a striped pulsar wind
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, observations of the Crab nebula for instance clearly indicate that most of the Poynting flux is eventually converted into ultra-relativistic particles. The mechanism responsible for transformation of the el...
متن کاملBinary Pulsar Shock Emissions as Galactic Gamma-ray Sources
We address several issues regarding the interpretation of galactic -ray sources. We consider powerful pulsars in binaries producing X-ray and gamma-ray unpulsed emission from the shock interaction of relativistic pulsar winds with circumbinary material. Nebular mass out ows from companion stars of binary pulsars can provide the right calorimeters to transform a fraction of the electromagnetic a...
متن کاملParticle acceleration and magnetic dissipation in relativistic current sheet of pair plasmas
We study linear and non-linear development of relativistic and ultrarelativistic current sheets of pair (e±) plasmas with anti-parallel magnetic fields. Two types of two-dimensional problems are investigated by particle-in-cell (PIC) simulations. First, we present the development of relativistic magnetic reconnection, whose outflow speed is an order of the light speed c. It is demonstrated that...
