Statistical description of the simulated FEB spectral events generated from the simulation described in Fig. 4, and corresponding to solution #2 from Table 1. Left: Doppler velocities of the FEB events occurring in the first 10⁵ yr after the end of the simulation. The velocity scale is on the left side of the plot; positive velocities correspond to redshifts. The simultaneous evolution of β Pic c’s argument of periastron ω_c,sky (see text) is superimposed in blue, with the corresponding scale in blue on the right side of the plot. The red bars highlight epochs where ω_c,sky matches the fitted value from Table 1. Right: histogram of FEB velocities occurring ±100 yr around epochs corresponding to the red bars.
