摘要：

We have constructed general relativistic models of a thin disk around a rotating black hole and computed profiles of a spectral line, emitted in the inner region of the disk. In our models we have also taken into account the self-gravity of the disk. The aim of this work is to study gravitational effects on the line profiles in connection with the X-ray features observed in spectra of active galactic nuclei. In some cases, the calculated profiles are clearly affected by the disk gravity, but relativistic dragging effects are found to be negligible.
