* NEW *

129 theoretical retrograde 3-body systems are shown in motion, including some systems with the outer orbit period equal to, or even shorter than, the inner orbit period.

**Computed light curve of a hypothetical eclipsing figure-eight triple star system**

The computed sequence of eclipses and the generalised shape of the light curve of a hypothetical eclipsing figure-eight triple star system.

**Computed radial velocity curves for the figure-eight orbit**

16 computed radial velocity curves for a hypothetical figure-eight triple star system. The curves have 2 or 3 maxima and 2 or 3 minima per orbital period, significantly different to binary star systems.

**A curious variation of the figure-eight orbit**

Stable figure-eight orbits for three stars, which together librate back and forth through almost pi/2 radians, and also precess through a full circle.
