Global Protoplanetary Disk Simulations: Dead Zone Formation and FUor Outbursts

Solar and Stellar Astrophysics 2021-01-25 v1 Earth and Planetary Astrophysics

Abstract

We conducted global hydrodynamic simulations of protoplanetary disk evolution with an adaptive Shakura-Sunyaev {\alpha} prescription to represent the layered disk structure, and starting with the collapse phase of the molecular cloud. With the canonical values of model parameters, self-consistent dead zones formed at the scale of a few au. The instabilities associated with the dead zone and corresponding outbursts, similar to FUor eruptions, were also observed in the simulations.
