From Jacob Shaham’s February 1987 Scientific American article “The Oldest Pulsars in the Universe:“
“[Radio pulsars] are thought to be rotating neutron stars: huge, spinning ‘nuclei’ that contain some 1057 protons and neutrons…. The large clump of nuclear matter, which has a mass about equal to that of the sun, is compressed into a sphere with a radius on the order of 10 kilometers. Consequently, the density of the star is enormous, slightly greater than the density of ordinary nuclear matter, which is itself some 10 trillion times denser than a lead brick. Currents of protons and electrons moving within the star generate a magnetic field. As the star rotates, a radio beacon, ignited by the combined effect of the magnetic field and the rotation, emanates from it and sweeps periodically through the surrounding space, rather like a lighthouse beam. Once per revolution the beacon cuts past the earth, giving rise to the beeping detected by radio telescopes.”
