Sidebands Due to Quasi-periodic Oscillations in 4u 1626−67
The low-mass X-ray binary pulsar 4U 1626−67 shows 0.048 Hz quasi-periodic oscillations (QPOs) and red noise variability as well as coherent pulsations at the 0.130 Hz neutron star spin frequency. Power density spectra of observations made with the Rossi X-ray Timing Explorer show significant sidebands separated from the pulsar spin frequency (and its harmonics) by the QPO frequency. These show ...
متن کاملDiscovery of KiloHertz Quasi-Periodic Oscillations in 4U 1735−44
We discovered a single kHz quasi-periodic oscillation (QPO) near 1150 Hz in the Rossi X-ray Timing Explorer X-ray light curve of the low mass X-ray binary and atoll source 4U 1735−44. The rms amplitude of this peak was 2–3 %, and the FWHM 6–40 Hz. There are indications that the kHz QPO frequency decreased from 1160 Hz to 1145 Hz when the count rate increased, which would be quite different from...
متن کاملMillihertz Optical/uv Oscillations in 4u 1626–67: Evidence for a Warped Accretion Disk1
We have detected large-amplitude 0.3–1.2 mHz quasi-periodic oscillations (QPOs) from the low-mass X-ray binary pulsar 4U 1626–67/KZ TrA, using ultraviolet photometry from the Hubble Space Telescope and groundbased optical photometry. These 1 mHz QPOs, which have coherence (ν/∆ν) ≈ 8, are entirely distinct from the 130 mHz pulsar spin frequency, a previously known 48 mHz QPO, and the 42 min bina...
متن کاملMillihertz Quasi-periodic Oscillations from Marginally Stable Nuclear Burning on an Accreting Neutron Star
We investigate marginally stable nuclear burning on the surface of accreting neutron stars as an explanation for the mHz quasi-periodic oscillations (QPOs) observed from three low mass X-ray binaries. At the boundary between unstable and stable burning, the temperature dependence of the nuclear heating rate and cooling rate almost cancel. The result is an oscillatory mode of burning, with an os...
متن کاملMillihertz Quasi-periodic Oscillations and Thermonuclear Bursts from Terzan 5: a Showcase of Burning Regimes
We present a comprehensive study of the thermonuclear bursts and millihertz quasi-periodic oscillations (mHz QPOs) from the neutron star (NS) transient and 11 Hz X-ray pulsar IGR J17480–2446, located in the globular cluster Terzan 5. The increase in burst rate that we find during its 2010 outburst, when persistent luminosity rises from 0.1 to 0.5 times the Eddington limit, is in qualitative agr...
