Modeling the Evolution of Protoplanetary Disks: Two Pathways from Gravitational Instability to MHD Wind-Driven Accretion
Yang Ni, Wenrui Xu, Xue-Ning Bai
The paper introduces a semi‑two‑dimensional model of protoplanetary disk evolution that includes gravitational instability, MHD winds, MRI, and radiative effects, and shows that th…

Global Simulations of Gravitational Instability in Protostellar Disks with Full Radiation Transport. I. Stochastic Fragmentation with Optical-depth-dependent Rate and Universal Fragment Mass
Wenrui Xu, Yan-Fei Jiang, Matthew W. Kunz +1
Fragmentation in a gravitationally unstable accretion disk can be an important pathway for forming stellar/planetary companions. To characterize quantitatively the condition for an…
