Vertical Structure of Neutrino-Dominated Accretion Disk and Applications to Gamma-Ray Bursts
arXiv:0912.3596 · doi:10.1088/0004-637X/709/2/851
Abstract
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 one or two orders of magnitude. The empty funnel along the rotation axis can naturally explain the neutrino annihilable ejection.
