Abstract:
Pseudo-Newtonian gravitational potential for spherically symmetric
black-hole space-times with a repulsive cosmological constant is applied
to equilibrium toroidal configurations of barotropic perfect fluid
orbiting black holes. The results are presented for marginally stable
barotropic tori with uniform distribution of the specific angular
momentum. For the adiabatic (isoentropic) perfect fluid, temperature
profiles, mass-density and pressure profiles are calculated.
