known as PSR J1915+1606 and PSR 1913+16) is a pulsar (a
radiating neutron star) which together with another neutron star
is in orbit around a common center of mass, thus forming a
binary star system. In 1974 it was discovered by Russell Alan
Hulse and Joseph Hooton Taylor, Jr., of the University of
Massachusetts Amherst. Their discovery of the system and
analysis of it earned them the 1993 Nobel Prize in Physics "for
the discovery of a new type of pulsar, a discovery that has
opened up new possibilities for the study of gravitation." The
system is also called the Hulse–Taylor binary pulsar after its
discoverers. Using the Arecibo 305m antenna, Hulse and Taylor
detected pulsed radio emissions and thus identified the source
as a pulsar, a rapidly rotating, highly magnetized neutron star.
The neutron star rotates on its axis 17 times per second; thus
the pulse period is 59 milliseconds. After timin
