Appendix A: Orbital parameters of the comets

In Table A.1, we show the orbital elements of the comets used during the dynamical studies in Sect. 5. They are extracted from JPL Horizons online solar system data.

Table A.1

Orbital parameters of the short-period comets under study.

Appendix B: Dust environment of the comets in the sample

In this Appendix, we present the evolution of the dust parameters versus heliocentric distance for each comet in the sample (Figs. B.1 to B.7). These parameters are dust production rate [kg/s], ejection velocities for particles of r = 1 cm glassy carbon spheres [m/s], the maximum size of the particles [cm], and the power index of the size distribution (δ). Solid red lines correspond to pre-perihelion, and dashed blue lines to post-perihelion.

Appendix C: Comparison between observational data and models

In this Appendix (Figs. C.1 to C.7), we show the comparison between the observational data and the models proposed in Sect. 4, which describe the dust environments of the comets of the sample, as in Fig. 5.
