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.
