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… (More)
