Warp and eccentricity propagation in discs around black holes
Barbara T. Ferreira, Gordon I. Ogilvie
We consider the inward propagation of warping and eccentric disturbances in discs around black holes under a wide variety of conditions. In our calculations we use secular theories…
Warped and eccentric discs around black holes
Gordon I. Ogilvie, Barbara T. Ferreira
Accretion discs around black holes in X-ray binary stars are warped if the spin axis of the black hole is not perpendicular to the binary orbital plane. They can also become eccent…
Excitation of trapped oscillations in discs around black holes
Barbara T. Ferreira, Gordon I. Ogilvie
High-frequency quasi-periodic oscillations detected in the light curves of black hole candidates can, according to one model, be identified with hydrodynamic oscillations of the ac…
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…
Subcritical dynamos in shear flows
F. Rincon, G. I. Ogilvie, M. R. E. Proctor +1
Identifying generic physical mechanisms responsible for the generation of magnetic fields and turbulence in differentially rotating flows is fundamental to understand the dynamics…
