The model requires a significant dust size evolution and a partially - evacuated inner disk region, as predicted by theories of planet formation. (arxiv.org)
These spontaneous traps then concentrate the grains coming from the outer disk regions, creating a very dense ring of solids, and giving a helping hand to the formation of planets. (sciencedaily.com)
I work on high - resolution spectroscopy of molecular gas emission and on millimeter interferometry of dust emission from planet - forming disk regions. (eos-nexus.org)
