Dissipation in Pulsar Winds
I review the constraints placed on relativistic pulsar winds by comparing optical and X-ray images of the inner Crab Nebula on the one hand with two-dimensional MHD simulations on the other. The various proposals in the literature for achieving the low magnetisation required at the inner edge of the Nebula, are then discussed, emphasising that of dissipation in the striped-wind picture. The pos...
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 کاملRadio Profile Instability in the Millisecond Pulsar PSR J0437−4715 due to Spiky Emission
The instability in one of the components of the radio integrated profile (IP) of the millisecond pulsar PSR J0437−4715 is correlated with the occurrence of the spiky emission in that component. It is speculated that the instability in other components is also due to the spiky emission. This might have important implications for interpreting the individual components of the IP as independent bea...
متن کاملNo Evidence for Coherent Diffractive Radiation Patterns in the Millisecond Pulsar PSR J0437−4715
An independent analysis of the 326.5 MHz data obtained by Ooty Radio Telescope reveals no evidence for coherent diffractive radiation patterns in the millisecond pulsar PSR J0437−4715.
متن کاملProperties and Evolution of the Redback Millisecond Pulsar Binary Psr J2129–0429
PSR J2129−0429 is a “redback” eclipsing millisecond pulsar binary with an unusually long 15.2 hr orbit. It was discovered by the Green Bank Telescope in a targeted search of unidentified Fermi gamma-ray sources. The pulsar companion is optically bright (mean mR=16.6mag), allowing us to construct the longest baseline photometric data set available for such a system. We present 10 years of arch...
