Relativistic models of kHz QPOs

Abstract

After reviewing the general-relativistic ``gap'' model of accretion, I discuss its relation to the high frequency quasi-periodic oscillations observed in low-mass X-ray binaries. The ``300'' Hz frequency seen in some X-ray bursts may be a relativistic signature of keplerian rotation of the neutron star.
