Measurements of second- and third-order relativistic effects in the orbit of binary pulsar PSR1913 + 16 have yielded self-consistent estimates of the masses of the pulsar and its companion, quantitative confirmation of the existence of gravitational radiation at the level predicted by general relativity, and detection of geodetic precession of the pulsar spin axis. 
Gravitational radiation of the binary pulsar PSR 1913 + 16
It is shown that in accordance with the relativistic tensor theory of the gravitational field in flat space-time the power of the gravitational radiation from the binary pulsar PSR 1913 + 16 exceeds

The two basic approaches to using binary pulsar measurements as probes of relativistic gravity are reviewed: the phenomenological (‘parametrized post-keplerian’ formalism) and the alternative-theory approach (multidimensional space of possible theories).
Experimental constraints on strong-field relativistic gravity
Experiments in our Solar System can test relativistic gravity only in the weak-field limit, but systems containing pulsars necessarily involve the effects of strong-field gravity. Timing observations
Gravitational radiation from an orbiting pulsar
We describe an experiment which establishes, with a high degree of confidence, the existence of gravitational radiation as predicted by general relativity. The experiment involves observations of
Determination of the Geometry of the PSR B1913+16 System by Geodetic Precession
New observations of the binary pulsar B1913+16 are presented. Since 1978 the leading component of the pulse profile has weakened dramatically by about 40%. For the first time, a decrease in component
A Study of the Two-body Problem with Magnetic Interactions
A first order correction is applied to Kepler’s third law that takes into account the magnetic interaction between two orbiting bodies. This correction is derived by introducing a magnetic moment
Possible optical observation of the companion star to the binary pulsar PSR1913 + 16
Deep R band CCD photographs of the region surrounding the binary pulsar PSR1913 + 16 have been obtained with the 4-m telescope of the Kitt Peak National Observatory. Using an accurate astrometric
Strong-field tests of general relativity
Until now, most experiments have succeeded in testing relativistic gravity only in its extreme weak-field limit. Because pulsars are neutron stars, with surface gravitational potentials GM/c2R=0.2,
Observations of Radio Pulsars
Pulsars, rapidly rotating highly magnetized neutron stars, have many exciting applications in physics and astronomy. After nearly 40 years since the original discovery, pulsar research has great


The binary pulsar - Post-Newtonian timing effects
Certain post-Newtonian effects may be observable in the arrival times of pulses from the binary pulsar PSR 1913+16. Such effects include the gravitational propagation delay and the post-Newtonian
Further observations of the binary pulsar PSR 1913+16.
We report the results of more than a year's timing observations of the binary pulsar PSR 1913+16. Within the accuracy of our measurements, about +- 300, the pulse arrival times are exactly
Arrival-time analysis for a pulsar in a binary system.
A method is described for analyzing the arrival times of pulses from the binary pulsar PSR 1913+16, in terms of the orbital elements and their possible secular variations. Estimates are given for the
The binary pulsar: physical processes, possible companions, and evolutionary histories.
A study of some aspects of the binary pulsar, PSR 1913+16, is presented in the light of recently reported observational results. If the companion to the pulsar gives a Newtonian contribution to the
The newly discovered pulsar PSR 1913 + 16, which has a period of approximately 0/sup 5/.059 and which undergoes periodic Doppler shifts, indicating that it is a member of a binary system, is
Gravitational radiation from binary systems in alternative metric theories of gravity - Dipole radiation and the binary pulsar
The generation of gravitational radiation in several currently viable metric theories of gravitation (Brans-Dicke, Rosen, Ni, and Lightman-Lee) is analyzed, and it is shown that these theories
