Gas flow around embedded planets
Planets embedded in protoplanetary disks perturb the surrounding gas. I simulate the resulting gas dynamics using the public hydrodynamics code Athena++.

Pebble accretion
Planets accrete millimeter- to centimeter-sized particles, known as pebbles. These pebbles are strongly coupled to the gas flow. I simulate pebble dynamics by post-processing hydrodynamical simulation data.

Gas accretion onto gap-opening planets
Giant planets undergo runaway gas accretion in the disk. I simulate the disk–planet interaction and the gas accretion process using the public hydrodynamics code Athena++.

Dust ring and gap formation by low-mass planets
Observed dust rings and gaps in protoplanetary disks may be signatures of forming planets. We show that an Earth-mass planet at 10 au can generate prominent dust rings and gaps. Image Credit: ALMA (/NRAO/ESO/NAOJ)
