Description
We revisit the vertical structure of neutrino-dominated accretion flows in spherical coordinates. We stress that the flow should be geometrically thick when advection becomes dominant. In our calculation, the luminosity of neutrino annihilation is enhanced by 1 or 2 orders of magnitude. The empty funnel along the rotation axis can naturally explain the neutrino annihilable ejection.
