N ov 2 00 7 A few remarks about the Pioneer anomaly
نویسنده
چکیده
Some features of the Pioneer anomaly are discussed in context of author’s explanation of this effect as a deceleration of the probes in the graviton background. It is noted that if the model is true then the best parameter of the anomalous acceleration should be not the distance to the Sun but a cosine of the angle between a velocity of the probe and its radius-vector. As it was reported by the authors of the discovery, NASA deep-space probes Pioneer 10/11 experience an anomalous constant acceleration directed towards the Sun (the Pioneer anomaly) [1, 2]. A possible origin of the effect remains unknown. In my model [3], any massive body must experience a constant deceleration w ≃ −Hc, where H is the Hubble constant and c is the light velocity, of the same order of magnitude as observed for cosmic probes. This effect is an analogue of cosmological redshifts in the model. Their common nature is forehead collisions with gravitons. I would like to consider here the main known features of this anomaly in context of my explanation keeping in mind present and future efforts to verify the reality of this effect and to understand it. The observed anomaly has the following main features: 1) in the range 5 15 AU from the Sun it is observed an anomalous sunward acceleration with the rising modulus which gets its maximum value, leastwise for Pioneer 11

The radio-metric Doppler tracking data from the Pioneer 10/11 spacecraft, from between 20-70 AU, yields an unambiguous and independently confirmed anomalous blue shift drift of at = (2.92± 0.44)× 10−18 s/s2. It can be interpreted as being due to a constant acceleration of aP = (8.74± 1.33)× 10−8 cm/s2 directed towards the Sun. No systematic effect has been able to explain the anomaly, even thou...

A model is presented in which the Pioneer anomaly is not related to the motion of the spaceship, but is a consequence of the acceleration of the cosmological proper time τ with respect to the coordinate parametric time t, i. e. of the value of d2τ/dt2 (> 0). Assuming flat spatial sections and that all the matter and energy is uniformly distributed throughout the universe, it is shown that this ...

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 ...
