Discovery of millihertz ultraviolet quasi-periodic oscillations in Hercules X-1
Observations of the ultraviolet continuum of the X-ray binary system Her X-1/HZ Herculis with the Space Telescope Imaging Spectrograph on the Hubble Space Telescope (HST) show quasi-periodic oscillations (QPOs) at frequencies of 8 ± 2 and 43 ± 2 mHz, with rms amplitudes of 2% and 4% of the steady fl...
