Signatures Produced by Other Physical Processes in Disks

Similar to the studies of planet-induced structures, I am also carrying out studies to examine observational signatures of various other physical processes in protoplanetary disks.

For example, If disks are massive enough to trigger the gravitational instability, they may develop symmetric pairs of spiral arms in scattered light that also closely resemble observations, as shown below.

My research interests lie primarily in the area of exoplanets and planet formation. I simulate observational signatures of planets forming in circumstellar disks, and compare them with real observations. My work is largely motivated by observations of disks taken by instruments such as ALMA , VLT/SPHERE, Gemini/GPI, Subaru/HiCIAO, and VLA.

My research is supported by the Natural Sciences and Engineering Research Council of Canada (NSERC) and the Alfred P. Sloan Foundation.

Observational Planet Formation

Planets form in gaseous protoplanetary disks surrounding newborn stars. As such, the best way to learn how they form observationally, is to watch them forming in disks. By doing so, we can directly address fundamental questions like when, where, and how do planets form. Specifically, many structures, such as gaps and spiral arms, have been resolved in protoplanetary disks; they are mostly likely associated with embedded (unseen) planets.
