pulsar wind nebula
A characteristic form, consisting of a bull's-eye ring pattern
and escaping jets, that is taken by radiation
and particles flowing away from some rapidly spinning neutron
stars at the heart of supernova
remnants (SNRs). The magnetic fields around the pulsar
accelerate the particles, forming jets in the vicinity of the poles of the
collapsed star and a ring flowing away from the pulsar's equatorial region.
Pulsar wind nebulae have been observed in the X-ray
region by the Chandra X-ray Observatory
around several young SNRs, including the Crab Nebula,
the Vela supernova remnant,
and SNR G54.01+0.3.
