Orbital models of high frequency QPOs
It is most often supposed that high frequency QPOs
originate in an orbital
motion near the inner edge of an accretion disk. We discuss recently
noticed strong restrictions to orbital QPO models following from the
analysis of QPO amplitude behaviour in a group of sources.
