摘要：
We investigate dust accumulation in elliptical vortices in a protoplanetary disk. We solved the equation of dust motion with gas drag, and obtain the dust surface density distribution in the vortex and mass enhancement factor in the planetesimal-forming region of the vortex. As a result, the mm-sized and cm-sized dust aggregates increase by a factor of 10 and 100, suggesting that the gravitational instability of dust layer in the vortices will occur.
