Quasiperiodic Oscillations in a Highly Magnetized Ultracompact X-Ray Binary 4U 1626-67
We report the detection of mHz quasiperiodic oscillations (QPOs) in four Nuclear Spectroscopic Telescope Array observations of 4U 1626–67 during its recent spin-down episode. By using a novel method based on the Hilbert–Huang transform, we present the first QPO-phase-resolved timing and spectral ana...
