Wave interference as the origin of the cyclic magnetorotational dynamo in accretion disks: insights from weakly nonlinear theory and local shearing box simulations
Uddipan Banik, Amitava Bhattacharjee, James M. Stone
Long-period cyclic reversals of the large-scale magnetic field are a prominent feature of the dynamo associated with the magnetorotational instability (MRI) in accretion disks, but…
The Interplay of Parametric and Magnetorotational Instabilities in Oscillatory Shear Flows
Callum W. Fairbairn, James M. Stone
The evolution of warped disks is governed by internal, oscillatory shear flows driven by their distorted geometry. However, these flows are known to be vigorously unstable to a hyd…
Cyclic Zoom: Multiscale GRMHD Modeling of Black Hole Accretion and Feedback
Minghao Guo, James M. Stone, Eliot Quataert +1
We present a ``cyclic zoom'' method to capture the dynamics of accretion flows onto black holes across a vast range of spatial and temporal scales in general relativistic magnetohy…
Life Cycles of Magnetic Fields in Stellar Evolution
D. Uzdensky, J. Arons, S. Balbus +5
This is a white paper submitted to the Stars and Stellar Evolution (SSE) Science Frontier Panel (SFP) of the NRC's Astronomy and Astrophysics 2010 Decadal Survey. The white paper i…
Shearing Box Simulations of the MRI in a Collisionless Plasma
Prateek Sharma, Gregory W. Hammett, Eliot Quataert +1
We describe local shearing box simulations of turbulence driven by the magnetorotational instability (MRI) in a collisionless plasma. Collisionless effects may be important in radi…
