AbstractTwin kHz quasi-periodic oscillations (QPOs) have been found in the emission spectra of about thirty X-ray neuron star systems, where the upper ones of twin QPOs are often interpreted as the Keplerian frequencies of the accreting matter orbiting around the central stars. The observations of the kHz QPOs can be used to constrain the masses of neutron stars (NSs), and in particular to imply the properties of the matters at nuclear densities. By the way, we discuss the preferences of some kHz QPO models that constrain the NS parameters.
