Preliminary simulation of the dynamics of the β Pic planetary system with only the two planets known to date, β Pic b (red) and β Pic c (blue), and the disk of planetesimals (black). The initial orbital parameters of β Pic b and c are taken from Table 1. Left: upper view of the system. The planetesimals are depicted by small black dots, and the orbits of the planets by colored dashed lines. Middle: view of the system in terms of semi-major axis and eccentricity. The planets are here represented by colored points. Right: radial profile of the planetesimal disk (solid black line), superimposed to the models of Augereau et al. (2001) (blue dotted line) and Dent et al. (2014) (red dotted line). Note the clear mismatch in the location of the inner edge between this simulation and observational models.
