Measuring mass and radius of neutron star using high-frequency quasi-periodic oscillations

High-frequency quasi-periodic oscillations are peaks detected in power spectra of several low-mass X-ray binaries. In this talk, I will discuss recent progress in understanding the origin of these peaks and how can we use them to measure the mass and radius of neutron star members of these binaries. Particular attention will be devoted to source 4U 1608-52 where other measurements of mass and radius are possible using X-ray bursts.
