The Impacts of GINGA Results on QPO Models
Abstract
Quasi-Periodic Oscillation (QPO) observations and the physical causes of QPO are studied. In the light of the recent results from Ginga observations, the physical properties required of QPO models are discussed and the existing QPO models are examined, especially the beat frequency model. The accretion torque theory in the context of the X-ray pulsar QPO is considered.
