Notes. An overview of the modelling assumptions introduced in Paper I. The check marks indicate whether these assumptions are still used in the present work.

^(a)

This assumption is investigated in more detail in Sect. 4.2.

^(b)

In Paper I, the dust survival time was assumed to be long (compared to the orbital period of the dust grains). Here, we assume instead that it is short (not much longer than one orbital period of the planet; see Sect. 2.3.2 for further details).
