Pulsed Radio Sources May Be Neutron Stars

At least three radio observatories have recently reported an entirely new type of radio source that emits pulses with extremely stable repetition frequency and apparently random amplitude. It is tempting to identify these sources as neutron stars, postulated but not yet observed, or as white dwarf stars. Observations with optical telescopes are under way to look for visible radiation from these sources and to see whether the same pulsation occurs.
