Selected Research Experience
MY WORK
My current work mainly focuses on the planet formation in the protoplanetary disks, especially the asymmetries and vortices within the disks.
VORTEX INDUCED RINGS AND GAPS IN PROTOPLANETARY DISKS
Supervised by Dr. Pinghui Huang and Dr. Ruobing Dong​
The co-existence of crescents and rings has been observed in protoplanetary disks in dust continuum emission. The crescents in continuum emission have been proposed to be the dust-trapping vortices generated by Rossby Wave Instability (RWI). We hypothesize that the RWI vortices could produce rings and gaps by driving density waves, analogous to planets. We study the properties of density waves and substructures induced by vortex in 2D hydrodynamic simulations for both global disks and shearing boxes performed by Athena++. In this work, we aim to find rings and gaps induced by vortices in disks comparable to observations.
