@article{Taylor1979MeasurementsOG, title={Measurements of general relativistic effects in the binary pulsar PSR1913 + 16}, author={J. H. Taylor and Lee A. Fowler and Peter Maxwell McCulloch}, journal={Nature}, year={1979}, volume={277}, pages={437-440} }
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.

Binary pulsars as probes of relativistic gravity
- PhysicsPhilosophical Transactions of the Royal Society of London. Series A: Physical and Engineering Sciences
