Circularization time (e1 < 0.01) for the HD 74156 system with I0 = 40° (red) and I0 = 50° (blue) using different values of the initial argument of the pericenter. For I0 = 40° the timescale decreases around the Lidov-Kozai equilibria, because the system is the circulation regime. For I0 = 50°, the system is in libration, but it is most likely destroyed after it crosses the separatrix.
