The magnetorotational instability originates from the elastic coupling of fluid elements in orbit around a gravitational well. Since inertial accelerations play a fundamental dynamical role in the process, one may expect substantial modifications by strong gravity in the case of accretion on to a black hole. In this paper, we develop a fully covariant, Lagrangian displacement vector field formalism with the aim of addressing these issues for a disc embedded in a stationary geometry with… Expand

The Magnetorotational Instability in the Kerr Metric
The magnetorotational instability (MRI) is the leading candidate for driving turbulence, angular momentum transport, and accretion in astrophysical disks. I consider the linear theory of the MRI in aExpand
Radiative heat conduction and the magnetorotational instability
A photon or a neutrino gas, semicontained by a non-diffusive particle species through scattering, comprises a rather peculiar magnetohydrodynamic fluid where the magnetic field is truly frozen onlyExpand
Black Hole Accretion Disks on the Edge
The local axisymmetric stability of hydrodynamical and magnetized, nearly Keplerian gaseous accretion disks around nonrotating black holes is examined in the vicinity of the classical marginallyExpand
Gravitational waves from hyper-accretion on to nascent black holes
We examine the possibility that hyper-accretion on to newly born black holes occurs in highly intermittent, non-asymmetric fashion favourable to gravitational-wave emission in a neutrino-cooled disc.Expand
Magnetorotational instability in neutron star mergers: impact of neutrinos
The merger of two neutron stars may give birth to a long-lived hypermassive neutron star. If it harbours a strong magnetic field of magnetar strength, its spin-down could explain several features ofExpand
Foundations of Black Hole Accretion Disk Theory
This review covers the main aspects of black hole accretion disk theory and discusses how accretion disks might reveal some of the unique signatures of strong gravity: the event horizon, the innermost stable circular orbit, and the ergosphere. Expand

We investigate the global stability of a differentially rotating fluid shell threaded by vertical and azimuthal magnetic fields to linear, axisymmetric perturbations. This system, which models aExpand
Local Axisymmetric Simulations of Magnetorotational Instability in Radiation-dominated Accretion Disks
We perform numerical simulations of magnetorotational instability in a local patch of accretion disk in which radiation pressure exceeds gas pressure. Such conditions may occur in the central regionsExpand
