Gravitational instability in protoplanetary disk with cooling: 2D global analysis
Zehao Su, Xing Wei
Self-gravity is important in protoplanetary disks for planet formation through gravitational instability (GI). We study the cooling effect on GI in a thin two-dimensional protoplan…

Dynamical Consequence of Shadows Cast to the Outer Protoplanetary Disks: I. Two-dimensional Simulations
Zehao Su, Xue-Ning Bai
There has been increasing evidence of shadows from scattered light observations of outer protoplanetary disks (PPDs) cast from the (unresolved) disk inner region, while in the mean…
