Unity project to model Keplerian motion in hierarchical multi-star systems.
For example, you can model a trinary system like this:
The blue line is drawn from the overall barycenter to the child node barycenter.
You can watch ephemeris data build up over time:
The escape menu provides helpful information and is displayed each time the application is run:
Each time a new system is created, the "candidate" stars are pulled from a data structure containing 1100 different spectral classes and luminousity types.
