Secular perturbation (Laplace-Lagrange)

What you are seeing: two coupled planets exchange eccentricity on the secular (long) timescale. The eccentricities oscillate as the eigenmodes beat against each other.

WHAT TO TRY

  • Vary each control and watch the rail readouts respond.
  • Compare the diagnostic plot against the live scene.
