Help with trinary star osloar system

[luxfaros]

Hello,
I have tried Alpha A and B with a barycenter and binary orbit as well as the sun with binary orbit to bary center but it won't last long.  Any one have a file or visual guide to help me?
Trying to test ideas for fantasy book im writing, not so great at math and physics.

I don't know if I could help, but I could try.  Usually it is the spacing of the stars that make unstable.  About how far are each of the stars from each other?

This video may help you.  Fast forward to 14 minutes for the part where he starts talking about trinary systems.

Thank you! this seems to be a good start.

Do you know of or have seen any trinary star systems where all the the suns move in a celtic trinity knot fashion?
I'm trying to recreate the solar system from the dark crystal

You can get some inspiration using these I made a while back:

But I'm afraid what you want won't be possible. Even with equal body parameters. Eventually one will get a ahead (or behind) and mess up the trinity. If it is an animation you are trying to do (to record it) you can leave the bodies on pause, and spin the camera.
