We calculate temperature profiles and X-ray spectra of accretion disks around rapidly rotating neutron stars considering the full effect of general relativity. Computed disk temperatures and luminosities are compared with the EXOSAT data to constrain the properties of five low-mass-X-ray-binary sources. We fit our model-spectra with an analytical function, which can in turn be used for routine spectral fitting work. Our equation-of-state dependent spectral model may be useful to constrain the equation-of-state models of neutron stars. We also compare the properties of a rotating neutron star with those of a rotating strange star with the hope of giving a possible way to identify a strange star, which will be important for the verification of strange-quark-matter hypothesis.
