Gravitational origin of the Pioneer Anomaly in metric theories of gravitation: can it be done without destruction of coherence between the theory and experiment in gravitational physics? |
|
Abstract |
From Doppler tracking data and data on circular motion of astronomical objects a metric of the Pioneer Anomaly is obtained. The metric gives a solution to problem of the manifest absence of anomaly acceleration in the orbits of the outer planets and extra-Pluto objects of the Solar system. However, it turns out that light deflection in the metric substantially differs from experimentally established, and the corresponding energy-momentum tensor of matter, which generates such a gravitational field in GR, violates energy dominance conditions. These strongly suggest a non-gravitational origin of the Pioneer Anomaly. |
