1. The term binary pulsar may refer to two pulsars in orbit around their mutual
center of gravity. The first such system to be discovered was PSR 1913+16,
also known as the Hulse-Taylor Pulsar.
2. More generally, abinary pulsar is any system in which a pulsar orbits another type of
star; examples include the Black Widow
Pulsar and Centaurus X-3.
