Overview of the simulations performed with various β and Q/m values. All simulations are done between 2010 and 2030, where densities and fluxes are binned per 100 days, and in a region of the solar system in a box of 22 AU around the Sun. The crosses denote these simulations (β and Q/m range), while the curves are three examples of β-curves: two from Kimura & Mann (1999) and one “adapted” astronomical silicates curve (Gustafson 1994). The β-curves relate the β-parameter of a material to its size. The sizes are consequently converted in corresponding charge-to-mass ratio, assuming a surface potential of +5 V and the material density according to the corresponding material (see Eq. (20)). The diamonds on the adapted astronomical silicates curve are 4 out of the 5 parameter combinations given in Table 3, that illustrate “realistic” sets of parameters for one material and their relation to particle size.
