MHD Simulation of a Disk Subjected to Lense-Thirring Precession
Kareem A. Sorathia, Julian H. Krolik, John F. Hawley
When matter orbits around a central mass obliquely with respect to the mass's spin axis, the Lense-Thirring effect causes it to precess at a rate declining sharply with radius. Eve…
Relaxation of Warped Disks: the Case of Pure Hydrodynamics
Kareem A. Sorathia, Julian H. Krolik, John F. Hawley
Orbiting disks may exhibit bends due to a misalignment between the angular momentum of the inner and outer regions of the disk. We begin a systematic simulational inquiry into the…
Global Simulations of Accretion Disks I: Convergence and Comparisons with Local Models
Kareem A. Sorathia, Christopher S. Reynolds, James M. Stone +1
Grid-based magnetohydrodynamic (MHD) simulations have proven invaluable for the study of astrophysical accretion disks. However, the fact that angular momentum transport in disks i…
Connections Between Local and Global Turbulence in Accretion Disks
Kareem A. Sorathia, Christopher S. Reynolds, Philip J. Armitage
We analyze a suite of global magnetohydrodynamic (MHD) accretion disk simulations in order to determine whether scaling laws for turbulence driven by the magnetorotational instabil…
