The fundamental difference between shear alpha viscosity and turbulent magnetorotational stresses
Martin E. Pessah, Chi-kwan Chan, Dimitrios Psaltis
Numerical simulations of turbulent, magnetized, differentially rotating flows driven by the magnetorotational instability are often used to calculate the effective values of alpha…
A Local Model for Angular Momentum Transport in Accretion Disks Driven by the Magnetorotational Instability
Martin E. Pessah, Chi-kwan Chan, Dimitrios Psaltis
We develop a local model for the exponential growth and saturation of the Reynolds and Maxwell stresses in turbulent flows driven by the magnetorotational instability. We first der…
The signature of the magnetorotational instability in the Reynolds and Maxwell stress tensors in accretion discs
Martin E. Pessah, Chi-kwan Chan, Dimitrios Psaltis
The magnetorotational instability is thought to be responsible for the generation of magnetohydrodynamic turbulence that leads to enhanced outward angular momentum transport in acc…
