Scientific paper

Dissipation of the energy of stars passing through the gaseous envelope of an active object at the center of a galaxy is shown to cause efficient capture of the stars if the envelope mass is comparable with the mass of the active object. A fairly high influx of stars in to the 'capture cone' region can be sustained if the stellar system is not spherically symmetric. An active object of high luminosity may initially exist in the form of a superstar. When the superstar attains a mass of over 300 million solar masses it will collapse, forming a massive black hole with a gaseous envelope.
