The Hulse–Taylor pulsar (known as PSR B1913+16, PSR J1915+1606 or PSR 1913+16) is a binary star system composed of a neutron star and a pulsar which orbit around their common center of mass. It is the first binary pulsar ever discovered.

The Binary Pulsar PSR 1913+16: In 1993, the Nobel Prize in Physics was awarded to Russell Hulse and Joseph Taylor of Princeton University for their 1974 discovery of a pulsar, designated PSR1913+16, in a binary system, in orbit with another star around a common center of mass.

The discovery of PSR1913+16, a binary pulsar system, brought light to the first indirect detection of gravitational waves in the early 1970s. This work, conducted by Joseph Taylor’s research team, which included graduate student Russell Hulse, led to the 1993 Nobel Prize in Physics.

radio-timing observations of a pulsar, PSR 1913+16, located in a binary star system with an orbital period of 7.75 hours. This object, discovered in 1974, has a pulse period of about 59 milliseconds that varies by about one part in 1,000 every 7.75 hours.

2016年6月3日 · We present relativistic analyses of 9257 measurements of times-of-arrival from the first binary pulsar, PSR B1913+16, acquired over the last thirty-five years.

The results indicate that at the present level of precision, the PSR 1913 + 16 can be modeled dynamically as a pair of orbiting point masses. Five Keplerian and five post-Keplerian orbital parameters are therefore mostly determined with remarkably high precision.

The existing observational data for the binary pulsar PSR 1913 + 16 are sufficient to give a rather well-defined model for the system. On the basis of evolutionary considerations, the pulsar must be a neutron star near the upper mass limit of 1.2 solar masses (M ⊙).

2010年11月2日 · We present results of more than three decades of timing measurements of the first known binary pulsar, PSR B1913+16. Like most other pulsars, its rotational behavior over such long time scales is significantly affected by small-scale irregularities not explicitly accounted for in a deterministic model.

Results are reported for more than a year's timing observations of the binary pulsar PSR 1913+16. Within the accuracy of the measurements, the pulse arrival times are exactly those expected from a clock of well-defined period moving in a Keplerian orbit with a constant rate of apsidal advance.

2004年7月7日 · We describe results derived from thirty years of observations of PSR B1913+16. Together with the Keplerian orbital parameters, measurements of the relativistic periastron advance and a combination of gravitational redshift and …
