Yep, that sums it up. Basically there's no way that I know of to calculate
stable orbits of stars and their planets in multiple star systems,
particularly when there's 3 or more stars. What I'll probably end up doing
is assigning the component stars a fixed position in a multiple-system
display. They just wont orbit each other. I dont think that will be a
huge setback as those orbits would normally be hundreds or thousands of
years long anyways. Planets can then be tested against those fixed planets
to see if neighboring stars knock them out of stable orbits.
