Canonical Timing and Spectral Behavior of LMC X-3 in the Low/Hard State
Patricia T. Boyd, Alan P. Smale, Jeroen Homan +3
We present results from three observations with the Rossi X-ray Timing Explorer (RXTE) of LMC X-3, obtained while the source was in an extended 'low/hard' state. The data reveal a…
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)…
The infrared counterpart of the Z source GX5-1
Peter G. Jonker, Rob P. Fender, Nigel C. Hambly +1
We have obtained UKIRT infrared observations of the field of the bright Galactic Z source GX5-1. From an astrometric plate solution tied to Tycho-ACT standards we have obtained acc…
Simultaneous Measurements of X-Ray Luminosity and Kilohertz Quasi-Periodic Oscillations in Low-Mass X-Ray Binaries
Eric C. Ford, Michiel van der Klis, Mariano Mendez +4
We measure simultaneously the properties of the energy spectra and the frequencies of the kilohertz quasi-periodic oscillations (QPOs) in fifteen low mass X-ray binaries covering a…
The power spectral properties of the Z-source GX 340+0
Peter G. Jonker, Michiel van der Klis, Rudy Wijnands +6
We present an analysis of ~390 ksec of data of the Z source GX 340+0 taken during 24 observations with the Rossi X-ray Timing Explorer satellite. We report the discovery of a new b…
