  1. 18. Exploring the Saturation of the MRI via Weakly Nonlinear Analysis
    Ms Susan Clark (Columbia University)
    05/08/2014, 14:00
    Workshop Main Programme
    Understanding the mechanism by which the magnetorotational instability (MRI) saturates is key to understanding the process by which it drives anisotropic MHD turbulence and transports angular momentum. Previous work has laid down the framework necessary to perform a weakly nonlinear analysis of the MRI near onset (that is, when the background magnetic field is just weak enough for the MRI to...

  2. 10. Magnetorotational instability saturation and transition to anisotropic turbulence
    Dr Gareth Murphy (Niels Bohr International Academy, NBI)

    Workshop Main Programme
    The magnetorotational instability (MRI) plays a key role in transfer of angular momentum outward in accretion disks. We study the growth of secondary parasite instabilities which trigger the saturation of the MRI. We examine the late linear stage of the MRI and transition to turbulence. We seek to gain a qualitative and quantitive understanding of the nature of the turbulence resulting from...

  3. 14. Locality and not locality in magnetized accretion flows
    Dr Alexander Hubbard (American Museum of Natural History)
    05/08/2014, 15:30
    Workshop Main Programme
    Theories of magnetically mediated accretion flows have focused on shearing radial magnetic field by orbital motions. We show that this generates dynamically important Poynting flux which transports energy radially. This means that disks are better thought of as layered slabs powered by their inner, accreting edge, rather than concentric annuli with vertical energy transport. We also...
