Comets as a possible source of nanodust in the Solar System cloud and in planetary debris discs

Abstract: Comets, comet-like objects and their fragments are the most plausible source for the dust in both the inner heliosphere and planetary debris discs around other stars. The smallest size of dust particles in debris discs is not known and recent observational results suggest that the size distribution of the dust extends down to sizes of a few nanometres or a few tens of nanometres. In the Solar System, electric field measurements from spacecraft observe events that are explained with high-velocity impacts of nan… Show more

“…Alternatively, one could speculate that the impacts from the sunward direction that RPC/IES observes are from minor solar wind constituents, as, for example, negative oxygen ions have energies of around 10 keV (cf. Mann 2017).…”

“…The relationship of the composition of the cometary grains to grains elsewhere, both in the solar system and the galaxy, was discussed both by Mann [46] and by Wooden [47]. The mineralogy appears to require multiple stages of condensation, presumably in the protoplanetary disc but many details of the picture are not clear and there remain many questions.…”
