Representative figure of the evolution of the dust parameter evolution obtained in the model versus the heliocentric distance for comet 30P/Reinmuth 1. The panels are as follows: a) dust mass-loss rate [kg/s]; b) ejection velocities for particles of r = 1 cm glassy carbon spheres [m/s]; c) maximum size of the particles [cm]; and d) power index of the size distribution. In all cases, the solid red lines correspond to pre-perihelion and the dashed blue lines to post-perihelion. In Appendix B, the results for each comet individually are displayed (see Figs. B.1 to B.7).
