Accretion Disks and Cosmic Rays

We model accretion disks as Faraday disks with current and mass flows perpendicular to 2D mean field flux surfaces. We model jets produced by accretion disks as weakly-unstable current flows. We model cosmic ray acceleration arising from jet kink modes producing a runaway ion beam that finally accelerates itself by cyclotron resonance. All of these processes can be unified by an Ohm's Law in which Spitzer resistivity is replaced by a generalized hyper-resisitivity, ultimately yielding several predictions in rough agreement with observations.
