Finding the Origin of the Pioneer Anomaly
Analysis of the radio tracking data from the Pioneer 10/11 spacecraft at distances between 20 70 AU from the Sun has consistently indicated the presence of an anomalous, small Doppler frequency drift. The drift can be interpreted as being due to a constant acceleration of aP = (8.74 ± 1.33) × 10 −8 cm/s directed towards the Sun. (A factor of 0.90 × 10 cm/s came from bias estimation). Although i...
متن کاملGravitational solution to the Pioneer 10/11 anomaly
A fully relativistic modified gravitational theory including a fifth force skew symmetric field is fitted to the Pioneer 10/11 anomalous acceleration. The theory allows for a variation with distance scales of the gravitational constant G, the fifth force skew symmetric field coupling strength ω and the mass of the skew symmetric field μ = 1/λ. A fit to the available anomalous acceleration data ...
متن کاملSupport for the thermal origin of the pioneer anomaly.
We investigate the possibility that the anomalous acceleration of the Pioneer 10 and 11 spacecraft is due to the recoil force associated with an anisotropic emission of thermal radiation off the vehicles. To this end, relying on the project and spacecraft design documentation, we constructed a comprehensive finite-element thermal model of the two spacecraft. Then, we numerically solve thermal c...
متن کاملCan the Pioneer Anomaly Be of Gravita- Tional Origin?
In order to satisfy the equivalence principle, any mechanism proposed to gravitationally explain the Pioneer anomaly, in the form in which it is presently known from the so-far analyzed Pioneer 10/11 data, cannot leave out of consideration its impact on the motion of the planets of the Solar System as well. In this paper we, first, use the latest determinations of the secular perihelion advance...

In order to satisfy the equivalence principle, any mechanism proposed to gravitationally explain the Pioneer anomaly, in the form in which it is presently known from the so-far analyzed Pioneer 10/11 data, cannot leave out of consideration its impact on the motion of the planets of the Solar System as well, especially those orbiting in the regions in which the anomalous behavior of the Pioneer ...
