Scientific paper

The paper investigates the interaction between the X rays emitted by the central source in the nucleus of a Seyfert galaxy or a quasar and the surface of the dense cluster of stars in which the central source is assumed to be embedded. The rate at which the stars in the cluster lose mass is estimated for the case where the central source is a supermassive black hole. It is shown that X-ray heating and ionization of the material in the stellar atmospheres affects the observed optical spectra of quasars and Seyfert nuclei.
