Abstract

The discovery of pulsar is an exciting discovery in 1960s, it has a profound influence on the development of modern physics. Although after the discovery of the first pulsar, it is quickly confirmed that pulsars are rapidly rotating neutron stars, yet people knew little about the essential mechanism leading neutron stars to pulse electromagnetic radiation. Thus, the author has analyzed the morphology and atmospheric environment of neutron stars, and found that a neutron star usually has two vortex structures located at its South pole and North pole, consisting of two groups of parallel spiral cloud paths, therefore producing two groups of corresponding dipole magnetic fields located at the South pole and the North pole respectively. It is the superposition of these two groups of dipole magnetic fields with the same polarity that form the neutron star’s magnetic field continuously giving off radio and X-ray pulsations in lighthouse-like beams. Since the atmospheric vortexes on the planets of the Solar System are tiny accretion disks, and the accretion disks on neutron stars, black holes or active galactic nuclei are essentially large-scale atmospheric vortexes, neutron star’s vortex-formation mechanism and electromagnetic radiation mechanism can be extended to the accretion and jets of black holes.
