  • We study the interaction between a dipolar magnetic field rooted in the central star and the circumstellar accretion disk in a classical T Tauri system. The MHD equations, including radiative energy transport, are solved for an axisymmetric system with a resistive, turbulent gas. A Shakura-Sunyaev-type eddy viscosity and a corresponding eddy magnetic diffusivity are assumed for the disk. The computations cover the disk and its halo in a radial interval from 1.7 to 20 stellar radii. The initial… CONTINUE READING
