Abstract

Early theories of active galactic nuclei concentrated on the physics of gas in the region dominated by the gravitational potential of a central black hole. Recently, attention has increasingly focussed on the role of individual stars in the environment of an active galactic nucleus. We investigate some aspects of accretion disc structure in active galactic nuclei containing a gravitationally significant stellar component. Because such discs radiate the gravitational binding energy released locally by viscous processes, their spectra probe the mass distributions of the regions where the discs reside
