Gravitoturbulent dynamos in astrophysical discs
A. Riols, H. Latter
The origin of large-scale and coherent magnetic fields in astrophysical discs is an important and long standing problem. Researchers commonly appeal to a turbulent dynamo, sustaine…
Magnetorotational instability and dynamo action in gravitoturbulent astrophysical discs
A. Riols, H. Latter
Though usually treated in isolation, the magnetorotational and gravitational instabilities (MRI and GI) may coincide at certain radii and evolutionary stages of protoplanetary disc…
Magnetorotationally driven wind cycles in local disc models
A. Riols, G. I. Ogilvie, H. Latter +1
Jets, from the protostellar to the AGN context, have been extensively studied but their connection to the turbulent dynamics of the underlying accretion disc is poorly understood.…
Magnetorotational dynamo chimeras. The missing link to turbulent accretion disk dynamo models?
A. Riols, F. Rincon, C. Cossu +3
In Keplerian accretion disks, turbulence and magnetic fields may be jointly excited through a subcritical dynamo process involving the magnetorotational instability (MRI). High-res…
Dissipative effects on the sustainment of a magnetorotational dynamo in Keplerian shear flow
A. Riols, F. Rincon, C. Cossu +3
The magnetorotational (MRI) dynamo has long been considered one of the possible drivers of turbulent angular momentum transport in astrophysical accretion disks. However, various n…
Global bifurcations to subcritical magnetorotational dynamo action in Keplerian shear flow
A. Riols, F. Rincon, C. Cossu +4
Magnetorotational dynamo action in Keplerian shear flow is a three-dimensional, nonlinear magnetohydrodynamic process whose study is relevant to the understanding of accretion and…
