Scientific paper

The brightness variability of Seyfert galaxies and quasars is one of the most direct pieces of evidence for the intrinsic smallness of the optical continuum source in these objects. If the power of a source varies with a time scale l: by a significant amount it must originate fram a region which cannot have a size much larger than c . l: across where c is the velocity of light; l: is observed to be typically of the order of months for such sources but may be much less. Not only the continuum strength but also the emission lines may vary in strength and shapes. This phenomenon is interesting with regard to the structure and kinematics of the line-emitting region as weil as to the radiation mechanism within the continuum source.
