Scalar potential model of the Pioneer Anomaly

Authors: John C. Hodge

The unexplained sunward acceleration $a_\mathrm{P}$ of the Pioneer 10 (P10) and the Pioneer 11 (P11) spacecraft remains a mystery. A scalar potential model (SPM) that derived from considerations of galaxy clusters, of redshift, and of H{\scriptsize{I}} rotation curves of spiral galaxies is applied to the Pioneer Anomaly. Matter is posited to warp the scalar potential $\rho$ field. The gradient of the $\rho$ field produces a force on matter and light. The changing $\rho$ along the light path causes the Pioneer Anomaly. The SPM is consistent with the general value of $a_\mathrm{P}$, with the annual periodicity, with the differing $a_\mathrm{P}$ between the spacecraft, with the slowly declining $a_\mathrm{P}$, with the low value of $a_\mathrm{P}$ immediately before the P11's Saturn encounter, with the high uncertainty in the value of $a_\mathrm{P}$ obtained during and after the P11's Saturn encounter, and with the cosmological connection suggested by $a_\mathrm{P} \approx cH_\mathrm{o}$. The effect of the $\rho$ field warp appears as the curvature of space proposed by general relativity.
