Neutrino-Driven Mass Loading of GRMHD Outflows

Astrophysics 2008-11-26 v1

Abstract

A GRMHD model of disk outflows with neutrino-driven mass ejection is presented. The model is used to calculate the structure of the outflow in the sub-slow magnetosonic region and the mass loading of the outflow, under conditions anticipated in the central engines of gamma-ray bursts. It is concluded that magnetic launching of ultra-relativistic polar outflows is in principle possible along low inclination field lines (with respect to the symmetry axis), provided the neutrino luminosity is sufficiently low, Lν\simlt1052L_\nu\simlt10^{52} erg s1^{-1}.
