Radial profiles of various density-weighted quantities at t = 110,700 rg/c. Many of the profiles change qualitatively at ≈200 rg, where the disk transitions from NTF dominated to NVF dominated (Figure 3). (a) Absolute magnetic field (“physical” components, Equation (2)) strength in the disk, weighted by r/rg for clarity. (b) Ratios of magnetic (pB), radiation (pr), and gas thermal (pt) pressures in the disk. (c) Three different measures of the dimensionless scale height H / r: the density scale height (Equation (8)), which indicates how vertically distributed the gas is; the gas thermal plus radiation pressure scale height (Equation (9)), which indicates how much gas thermal and radiation pressure (where pr ≫ pt) support the disk; and the magnetic scale height (Equation (12)), which indicates how much magnetic pressure supports the disk. (d) Disk velocities (“physical” components, Equation (2)) normalized to the velocity of circular orbits (vc, Equation (11)). We depict the azimuthal velocity vφ, the net radial velocity −vr, and the net radial velocity of all inflowing gas −vr,in. (e) Mass accretion rate (﹩\dot{M}﹩, Equation (13)) normalized to the Eddington accretion rate (﹩{\dot{M}}_{{\rm{Edd}}}﹩, Equation (15), assuming radiative efficiency η = 0.1). We also plot separate profiles of the inflowing and outflowing mass transport rates.
