Abstract
Born amid the violence of supernova explosions, neutron stars are the extremely dense endpoints of stars that initially had a mass of more than about 18–10 M⊙ (M⊙ is the mass of the Sun, about 2×1033 g). During its final collapse, such a star expels most of its material, leaving behind a remnant—a neutron star—packing a typical mass of 1.4 M⊙ into a radius of only 10 km. With a density comparable to that of an atomic nucleus, a neutron star provides an extreme environment for fast and violent phenomena: Matter orbiting a neutron star can have a period as short as a millisecond; when it crashes into the star (that is, when it is “accreted”), this matter can be moving at one-third the speed of light. Because their behavior can vary over readily observable time scales, neutron stars can be rich sources of information about nuclear physics, general relativity and astrophysics.
