Binary Pulsar Tests of General Relativity in the Presence of Low-Frequency Noise Sergei M. Kopeikin1,2 and Vladimir A. Potapov3 Abstract. The influence of the low-frequency timing noise on the preci- sion of measurements of the Keplerian and post-Keplerian orbital param- eters in binary pulsars is studied. Fundamental limits on the accuracy of tests of alternative theories of gravity in the strong-field regime are established. The gravitational low-frequency timing noise formed by an ensemble of binary stars is briefly discussed. 1 Dept. of Physics Astronomy, University of Missouri-Columbia, Columbia, MO65211, USA 2 On leave: ASC FIAN, Leninskii Prospect 53, Moscow, Russia 3 PRAO, ASC FIAN, Leninskii Prospect 53, Moscow, Russia 1. Background The discovery of the first binary pulsar in 1974 by R. Hulse and J.H. Taylor had opened fascinating new opportunities for testing alternative theories of gravi- tation in the radiative and in the strong-gravitational-field regimes outside the boundaries of the Solar system. Presently, two distinguished binary pulsars - PSR B1913+16 and PSR B1534+12 - serve as primary extra-solar astrophys- ical laboratories for gravitational physisists. The radiative ω? ? γ ? P?b test of General Relativity (GR) in the case of PSR B1913+16 has been performed with a precision about 0.4% (Taylor Weisberg 1989, Damour Taylor 1991). In addition, the binary pulsars PSR B1534+12 strong-field ω? ? γ ? s test of GR has been done with the precision 1% (Stairs et al. 1998). What is worth noting is that the binary pulsar tests of GR have been carried out with an accuracy being comparable to, or in some aspects, higher than the GR tests in the Solar system which have been always performed in the near, weak-field zone of the solar system gravitating bodies.
