Mean eccentricity of the particles in the disc for the SPH simulation (black), in the N-body simulation (purple), and as expected from the theory presented in Sect. 2.2 (green, using Eqs. (2) and (7)). The vertical dashed line indicates τe as calculated from Eq. (8) for half the truncation radius (see Sect. 4.2). The left column shows the simulations with a density of 1.9 × 10-18 g/cm3 and the right column the simulations with a density of 1.9 × 10-17 g/cm3.
