Fourteen-year observations of the binary pulsar PSR 1913 + 16 provided data consistent with a straightforward model allowing for the motion of the earth, special and general relativistic effects within the solar system, dispersive propagation in the interstellar medium, relativistic motion of the pulsar in its orbit, and deterministic spin-down behavior of the pulsar itself. Pulsar PSR B1913+16 (PSR J1915+1606) was the first binary pulsar to be discovered (Hulse & Taylor 1975).

Since 1978 the leading component of the pulse profile has weakend dramatically by about 40%. The other test, the periastron drift of a binary pulsar's orbit, is a rather large effect, because while the shift per orbit is only of order GM/ac 2 = 10 −6, the binary pulsar completes of order 1,000 orbits per year. It was discovered using the Arecibo 305m antenna. An example of this type of binary pulsar is the celebrated PSR B1913+16, whose orbit is decaying due to the emission of gravitational radiation. 3.1.
