Scientific paper

The fluorescent line emitted from an accretion disk around a rotating black hole is examined. The line profiles for various models with inclination angle, Kerr parameter, and disk parameters are given. If the emitting region is highly localized to the inner part, r less than 20 GM/sq c, the difference due to the black hole rotation appears in the line profiles. Otherwise, the difference is hidden due to photons emitted from larger radii, where the propagation of the radiation and the disk structure are almost independent of the Kerr parameter.
