Tests of GR using Pulsar Timing (Remote Talk)

The great stability of pulsar periods, especially millisecond pulsars, and the existence of pulsars in
binary systems makes possible a range of tests of theories of relativistic gravitation, in particular,
Einsteinís general theory of relativity (GR). In this talk I will concentrate on GR tests made using
timing observations of the Double Pulsar, PSR J0737-3039A/B. These have enabled measurement of
six relativistic parameters, giving five independent tests of GR. They have also revealed the effects
of Lense-Thirring precession and gravitational light-bending leading to constraints on the moment
of inertia of the neutron star.
