... What is a pulsar? ... For young pulsars with superstrong magnetic fields ( ) and hot polar caps (with temperature of ), because of the energy loss of electrons or positrons due to resonant inverse Compton scattering in the vicinity of polar caps, pair cascades occur at distances further away from the polar cap, and in this case, we have a relatively high acceleration efficiency with ions carrying most of the particle luminosity. ... Limits on particle energies by resonant inverse Compton scattering ...

... Right: Schematic of disk reprocessing in X-ray pulsars. The hard (power-law spectrum) X-ray beam sweeps around and illuminates the accretion disk, which reradiates a soft X-ray (blackbody) component. ... X-ray binaries owe their prominence to one of the most efficient energy release mechanisms known: accretion onto a compact object. In the accretion process gas from the atmosphere of the less dense companion is accelerated toward the extremely dense compact star. ...

... According to modern views on the evolution and origin of stars, most of the stars are members of binary systems. ... After the second explosion, the pairs tend to break up and neutron stars and/or black holes fly apart. High velocities of radio pulsars are apparently largely due to this effect. ...

. A gamma-ray pulsar is a compact neutron star that accelerates charged particles to relativistic speeds in its extremely strong magnetic field. This process produces gamma radiation (violet) far above the surface of the compact remains of the star, while radio waves (green) are emitted over the magnetic poles in the form of a cone. The rotation sweeps the emission regions across the terrestrial line of sight, making the pulsar light up periodically in the sky. б© NASA/Fermi/Cruz de Wilde
