This page contains links to the various mpegs that
were produced using the GRMHD code to
study the accretion of magnetized gas into black holes via the Magneto-rotational
Instability (MRI).
Initial torus configuration is the general relativistic
version near-Keplerian torus of Hawley (2000) that was subsequently studied
by Hawley and Krolik (2001, 2002) in a pseudo-Newtonian potential. Initial
magnetic field configuration is poloidal loops, with beta=100 in all but
one model, where beta=200 (see Table 1 in preprint for more information
on model parameters). We designate these the KD models because of the properties
of their initial angular momentum distribution.
The movies linked in the left margin show animations
at ~30 frames per orbit, following 10 orbits (at pressure maximum) of the
evolution of a magnetized torus orbiting a black hole. The 3D views are
animations of gas density (linear scale - red maximum, blue minimum).
The 2D views are scaled logarithmically, over 4 decades from the initial
density maximum.
NOTE:
These are direct animations in the Boyer-Lindquist coordinate system. Fully
ray-traced images are "in the works". Also note that these mpegs are compressed
from several GB of data... loss of image quality is inevitable.
KD0 - Torus and Schwarzschild Black Hole
The movies linked in the marging are: 1) 3D view
of the density in the inner region of the accretion flow (triangular patterns
at inner edge are an artifact), and 2) a view of a 2D poloidal slice
of density for the inner region of the flow.
KDP - Prograde Torus and Kerr Black
Hole
The movies linked in the marging are: 1) 3D view
of the density in the inner region of the accretion flow (triangular patterns
at inner edge are an artifact), 2) a full view of a 2D poloidal
slice of density, 3) a view of a 2D poloidal slice of density
in the inner region, and 4) a view of a 2D equatorial slice of density
in the inner region.
