Description
In this talk we report on our recent calculation of the measurements of mass and radius of the neutron star in low-mass X-ray binary 4U1608-52. We combine our measurements based on modelling of kHz quasi-periodic oscillations using cusp-torus model and constraints from modelling of X-ray bursts by other authors. We show that kHz QPOs depend strongly on the mass of the source which combines well with the radius constraints from X-ray bursts.
