The impact of accretion heating and thermal conduction on the dead zone of protoplanetary disks [PDF]
The Astrophysical Journal,881:56(10pp), 2019 August 10, 2021 The paper investigates the influence of accretion heating and turbulent heat conduction on the equilibrium of protoplanetary disks, extending the 2D axis-symmetric passive disk model of Flock (Flock et al. 2016, ApJ 827, 144). The model includes dust sublimation and radiative transfer with the flux-limited diffusion approximation, and predicts the ...
