4U 1608-52 and 4U 1636-53, and the origin of the kHz QPOs in LMXBs

M. Mendez

Abstract

I review the available RXTE data of the two low-mass X-ray binaries (LMXBs) and atoll sources 4U 1608-52 and 4U 1636-53. I summarize the properties of the quasi-periodic oscillations at kilohertz frequencies (kHz QPOs) observed in their X-ray flux, and how do they relate to other properties of the sources, e.g., X-ray flux, inferred mass accretion rate, etc. I show that a simple beat-frequency model cannot explain the kHz QPOs in these two sources. In view of the great similarity of the kHz QPO phenomenology in all LMXBs, this conclusion also applies to the phenomenon as observed in other LMXBs.
