Radiative Heat Conduction and the Magnetorotational Instability
Rafael A. Araya-Gochez, Ethan Vishniac
A photon or neutrino gas--semi-contained by a baryonic species through scattering--comprises a rather peculiar MHD fluid where the magnetic field is truly frozen only to the co-mov…
Problems and Progress in Astrophysical Dynamos
E. T. Vishniac, A. Lazarian, J. Cho
Astrophysical objects with negligible resistivity are often threaded by large scale magnetic fields. The generation of these fields is somewhat mysterious, since a magnetic field i…
Reconnection via the Tearing Instability
A. Lazarian, Ethan T. Vishniac
We discuss the role of tearing instabilities in magnetic reconnection. In three dimensions this instability leads to the formation of strong Alfvenic waves that remove plasma effic…
The Dynamics of Flux Tubes in a High Beta Plasma
E. T. Vishniac
We suggest a new model for the structure of a magnetic field embedded high turbulent plasma, based on the popular notion that the magnetic field will tend to separate into indi…
Why Disks Shine: the Transport of Angular Momentum in Hot, Thin Disks
E. T. Vishniac
I review recent work on the radial transport of angular momentum in ionized, Keplerian accretion disks. Proposed mechanisms include hydrodynamic and MHD local instabilities and lon…
Does Dissipation in AGN Disks Couple to the Total Pressure?
E. T. Vishniac
Recent work on the transport of angular momentum in accretion disks suggests that the Velikhov-Chandrasekhar instability, in which a large scale magnetic field generates small scal…
