Localized magnetorotational instability and its role in the accretion disc dynamo
G. Lesur, G. I. Ogilvie
(Abriged) The magnetorotational instability (MRI) is believed to be an efficient way to transport angular momentum in accretion discs. It has also been suggested as a way to amplif…
On Self-Sustained Dynamo Cycles in Accretion Discs
G. Lesur, G. I. Ogilvie
(abridged) MHD turbulence is known to exist in shearing boxes with either zero or nonzero net magnetic flux. However, the way turbulence survives in the zero-net-flux case is not e…
Impact of dimensionless numbers on the efficiency of MRI-induced turbulent transport
G. Lesur, P-Y. Longaretti
The magneto-rotational instability is presently the most promising source of turbulent transport in accretion disks. However, some important issues still need to be addressed to qu…
On the relevance of subcritical hydrodynamic turbulence to accretion disk transport
G. Lesur, P-Y. Longaretti
Hydrodynamic unstratified keplerian flows are known to be linearly stable at all Reynolds numbers, but may nevertheless become turbulent through nonlinear mechanisms. However, in t…
