Magnetohydrodynamic model of Crab nebula radiation

The authors calculate the properties of the synchrotron continuum expected on the basis of a steady spherically symmetric MHD model of the flow in the Crab nebula. The model accounts for the spectral distribution of the continuum from the optical to γ-rays, and semiquantitatively for its observed spatial distribution. The model does not account for the radio portion of the Crab nebula's spectrum.
