The Crab Nebula pulsar conforms to the model of a rotating magnetised neutron star in the rate of energy generation and the exponent of the rotation law.
It is suggested that the main pulse is due to electrons and the precursor to protons. Both must radiate in coherent bunches. Optical and X-ray radiation is by the synchrotron process.
The wisps observed in the Nebula may represent the release of an instability storing about 1043 erg and 1047–48 particles.
Finally, some considerations are made about the general relation between supernova remnants and rotating neutron stars.
