MONDian three-body predictions for LISA Pathfinder
  In previous work it was shown that MOND theories predict anomalously strong
tidal stresses near the saddle points of the Newtonian gravitational potential.
An analytical examination of the saddle between two bodies revealed a linear
and a non-linear solution, valid for the outer and inner regions. Here we
present a numerical algorithm for solving the MOND equations. We check the code
against the two-body analytical solutions and explore the region transitioning
between them. We then develop a a realistic model for the MONDian effects on
the saddles of the Sun-Earth-Moon system (including further sources is
straightforward). For the Sun-Earth saddle we find that the two-body results
are almost unchanged, with corrections increasing from full to new Moon. In
contrast, the Moon saddle is an intrinsically three-body problem, but we
numerically find a recipe for adapting the two-body solution to this case, by
means of a suitable re-scaling and axis re-orientation. We explore possible
experimental scenarios for LISA Pathfinder, and the prospect of a visit to the
saddle(s) at the end of the mission. Given the chaotic nature of the orbits,
awareness of the full range of the possibilities is crucial for a realistic
prediction. We conclude that even with very conservative assumptions on the
impact parameter, the accelerometers are abundantly sensitive to vindicate or
rule out the theory.
