Discovery of a new, third kHz QPO in 4U 1608-52, 4U 1728-34, and 4U 1636-53. Sidebands to the lower kHz QPO?
Peter G. Jonker, Mariano Mendez, Michiel van der Klis
We report the discovery of a third kilohertz quasi-periodic oscillation (kHz QPO) in the power spectra of the low-mass X-ray binaries 4U 1608-52 (6.3 sigma), 4U 1728-34 (6.0 sigma)…

Timing the Kilohertz Quasi-Periodic Oscillations in Low-mass X-ray Binaries
Mariano Mendez
I describe a new technique that we have been using in the past few years to get precise measurements of the frequency separation of the kHz QPOs in some Low-mass X-ray binaries. I…
