Accretion disk density stucture at 7.6 s

The density in the central regions of Model 14A 7.60 seconds after core collapse. A dense disk (red, 10**9 g/cm**3) of gas is accreting into the black hole. The centrifugally supported torus has a radius of 200 km. Still higher densities exist in the disk inside the inner boundary of our calculation (50 km). Gas is accreting much more readily along the polar axis due to the lack of centrifugal support and has left behind a channel with relatively low density (blue, 10**6 g/cm**3). Should energy be deposited near the black hole, this geometry will naturally focus jets along the rotational axis.
