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

Pebble accretion
Planets accrete approximately mm to cm sized particles (pebbles). Pebbles are dragged by gas flow. I simulate pebble dynamics combined with hydrodynamical simulation data.

Gas accretion onto gap-opening planets
Giant planets accrete gas in a runnaway fashin. I simulate the disk-planet interaction and gas accretion process with the public hydrodynamic code Athena++.

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