Modulation mechanisms of high-frequency QPOs
Two fundamental questions that need to be answered in the context of any QPO theory are: how QPOs are excited, and how flux is modulated. I will
address the second issue and will discuss possible modulation mechanisms
for both neutron-star and black-hole type of HFQPOs that may be
responsible for the actual outgoing flux modulation.@
