Depiction of the maximum Lyapunov exponent (colour coded) for various mass ratios μ and initial conditions ρ₀ using a linear scale (left) or a logarithmic scale (right) where  − n corresponds to 10 ^− n. Crosses denote cases where the simulation was terminated due to the planet being captured by one of the stars or being ejected from the system. Green, red, and black curves represent the initial conditions that cause the ZVC to open at L1, L2, and L3, respectively.
