I did see where the ...lovers Guide to Pern had a diagram of the Red Star orbit.

By modelling it- and I'll have to get the dlg as a reference- I can get some more information- and my own pretty pictures!

might be raising a post from the dead, however, it was a point that Aivas did three explosive insertions on the red star. With Jaxom and Ruth's help he could and did put two engines when and where he wanted them. the last engine finished nudging the red star into a stable orbit. theoretically.

Edith, From what I recall, a Lagrange point is a point of zero net gravity. its formed by the gravitational pull of various bodies being equal in magnitude but opposite vector. I'm not even sure there would be any stable ones for Pern since it has a pair of moons with varying orbital speeds.
