Query: Structure and Nuclear Composition of General Relativistic,
  Magnetohydrodynamic Outflows from Neutrino-Cooled Disks   We compute the structure and degree of neutronization of general relativistic
magnetohydrodynamic (GRMHD) outflows originating from the inner region of
neutrino-cooled disks. We consider both, outflows expelled from a hydrostatic
disk corona and outflows driven by disk turbulence. We show that in outflows
driven thermally from a static disk the electron fraction quickly evolves to
its equilibrium value which is dominated by neutrino capture. Those outflows
are generally proton rich and, under certain conditions, can be magnetically
dominated. They may also provide sites for effective production of 56Ni.
Centrifugally driven outflows and outflows driven by disk turbulence, on the
other hand, can preserve the large in-disk neutron excess. Those outflows are,
quite generally, subrelativistic by virtue of the large mass flux driven by the
additional forces.
