  • Longer description:
    The composition and structure of comet nuclei are poorly known, and cannot be easily determined from ground observations.
    For this reason, we developed different models of comet nuclei to test different parameters and hypotheses.

    Parameters used in these simulations are derived from the observations when available, or chosen among those that are considered typical for comets (Rickman and Huebner,1990, Huebner et al., 1999).

    More specifically, we have tested the influence of dust distributions (exponential, large grains and Gaussian).
    The primordial distribution consists of 5 classes from 1 Ám to 1 cm with a Gaussian distribution; the Exponential one follows a power index -4 (6 size classes from 1 Ám to 1 cm) with the first class being most numerous; the Big grains distribution has 6 classes, from 1 Ám to 10 cm to see the effects of very large grains.
