Geodesic model complience with the frequencies of the observed X-ray quasi-period oscillations of XTE J1807-294

Abstract

The investigation of the data for quasi-periodic pulsations observed in the X-ray spectra of the accreting millisecond pulsar XTEJ 1807-294 allows some conclusions to be made about its main parameters - mass and angular momentum. Seven different geodesic models - namely RP, RP1, RP2, TP, TP1, WD and TD are applied in attempt to assess their ability to describe the properties of the central neutron star.
