Quasi-periodic Oscillations

  • Quasi-periodic oscillations: rapid varibility in the light-curves of low-mass X-ray binaries (and some other objects)
  • Centroid frequency and intensity of oscillations depends on state of source, as plotted on a "colour" diagram
  • QPO offer insight into the accretion process in compact objects
