Three-dimensional, dust-plus-gas simulation of a protoplanetary disk with an embedded planet. As the planet carves a gap in the disk, dust grains are elevated to high altitudes. Unlike simple 2D models of disk-planet interaction, these simulations show that the dynamics around planet gaps, specifically the dust distribution, is fully three-dimensional, and thus will have important observational implications.

Puffed up dust at planet gaps

Moment-2 image for the 13C18O J = 3–2 transition of the fiducial model at face on. The location of the circumplanetary disk is labeled. A 4×10-3 stellar mass planet induces a prominent ring of high velocity dispersion inside the gap. This is the key planet-induced signature in this study (Dong, Liu, & Fung 2019).
