Same as in Fig. 9, except for μ = 5 × 10^-5. In this case, a test mass starting at ϖ = 0 and e = 0.05 can fall into the star even considering the General Relativity contribution. The level curves of the purely planetary Hamiltonian do not change with different values of μ: as explained in the text, here μ only plays the role of setting the timescales of the evolution of the test particle, not the evolution itself.
