Over 550 pulsars are now known, almost all detected at radio frequencies which capture their distinctive bursts of electromagnetic energy. These pulse periods range from 1.5 milliseconds to several seconds.
Most pulsars are single neutron stars but they can also exist in a binary orbit with a companion.
Observations have revealed a wealth of detail about the structure and evolution of pulsars and the pulse-emission process, giving new insight into the behavior of matter in the presence of extreme gravitational and electromagnetic fields. In fact, pulsars have unique physical properties which make them nearly ideal as probes for a wide range of physical studies. Publication dates and prices are subject to change without notice.
