Evolution of self-gravitating magnetized disks. II- Interaction between MHD turbulence and gravitational instabilities
Sebastien Fromang, Steven A. Balbus, Caroline Terquem +1
We present 3D magnetohydrodynamic (MHD) numerical simulations of the evolution of self--gravitating and weakly magnetized disks with an adiabatic equation of state. Such disks are…
Magnetically Driven Accretion in the Kerr Metric III: Unbound Outflows
Jean-Pierre De Villiers, John F. Hawley, Julian H. Krolik +1
We have carried out fully relativistic numerical simulations of accretion disks in the Kerr metric. In this paper we focus on the unbound outflows that emerge self-consistently fro…
Magnetically Driven Accretion Flows in the Kerr Metric II: Structure of the Magnetic Field
Shigenobu Hirose, Julian H. Krolik, Jean-Pierre De Villiers +1
We present a detailed analysis of the magnetic field structure found in general relativistic 3D MHD simulations of accreting tori in the Kerr metric with different black hole spins…
Evolution of self-gravitating magnetized disks. I- Axisymmetric simulations
Sebastien Fromang, Steven A. Balbus, Jean-Pierre De Villiers
In this paper and a companion work, we report on the first global numerical simulations of self-gravitating magnetized tori, subject in particular to the influence of the magnetoro…
Magnetically Driven Accretion Flows in the Kerr Metric I: Models and Overall Structure
Jean-Pierre De Villiers, John F. Hawley, Julian H. Krolik
This is the first in a series of papers that investigate the properties of accretion flows in the Kerr metric through three-dimensional, general relativistic magnetohydrodynamic si…
Global General Relativistic Magnetohydrodynamic Simulations of Accretion Tori
Jean-Pierre De Villiers, John F. Hawley
This paper presents an initial survey of the properties of accretion flows in the Kerr metric from three-dimensional, general relativistic magnetohydrodynamic simulations of accret…
