A binary pulsar is a pulsar rotating in orbit about a center of mass with one other companion, which is typically another pulsar, neutron star, or white dwarf. The strong gravitational field is of interest to physicists, and numerous binary pulsars have been discovered in recent decades.[1]
In 1974 Professors Taylor ahd Hulse discovered the first binary pulsar, PSR 1913 16, also known as the "Hulse-Taylor binary pulsar."
