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.
