Repin (IKI) and Alexander F. Zakharov (ITEP) Recent observations of Seyfert galaxies, carried out by ASCA and RXTE seem to indicate that the broad iron $K_\alpha$ line (6.4 keV) takes its origin in the innermost area of the accretion disk around a supermassive black hole. In the region $(1 - 3)r_g$, where the line is assummed to arise the effects of General Relativity (GR) should be taken into account. A spectrum of a solitary emission line of a hot spot in the Kerrian accretion disk has been simulated, depending on the radial coordinate $r$ and the angular momentum $a=J/M$ of a black hole, under the assumption of equatorial circular motion of a hot spot. It is shown that the characteristic two-peak line profile with the sharp edges arises at a large distance, (about $r \approx (3-10)r_g$) or large inclination angle. The inner regions emit the line, which is observed at the infinity with one maximum and extremely wide red wing. The disk spectrum is simulated then as a sum of the thin rings spectra. It is shown also that the angular momentum $a$ is a difficult parameter for the immediate measurements. Only the high accuracy future spectral observations, being carried out, could detect this quantity. ------=_NextPart_000_0005_01BF7D79.2974D2A0--
