Abstract: This paper test the predictive power of a recently developed relativistic magnetohydrodynamic model of pulsar wind nebulae with a double-torus X-ray morphology. The model predicts that the highly magnetized flows of the nebula should be quasi-laminar and split into two as they approach its outer boundary. This prediction is shown to be supported by archival data from the Chandra X-ray telescope, which observed Vela, a double-torus X-ray nebula inflated by the pulsar PSR J0835-4510 in the constellation Vela. The model also explains the origin of part of the diffuse X-ray emission of the Vela.

Keywords: MHD, pulsar wind nebulae, supernova remnants, X-ray astrophysics.
