PSR B1259-63

A radio pulsar in orbit of a type Be star known as SS 2883 in the SS 2883 system. What makes the binary system of interest is PSR B1259-63's orbit, which takes it through a vast dust ring around SS 2883 twice every 3.4 standard years. The plunges are only a few months apart, just before and after periastron, the point when the two objects in orbit are closest to each other. During the plunges, high amounts of X-rays and Gamma rays are emitted.
