  - "Context. X-ray binaries exhibit complex variability patterns studied in the power
    spectrum. These include the broadband noise (BBN)\r\ncomponents and various types
    of narrow components called quasi-periodic oscillations (QPOs). There is currently
    no consensus about\r\nwhat determines the presence or absence of the BBN or what
    generates the QPOs. Many believe that QPO generation is due to framedragging effects
    caused by Lense–Thirring torques.\r\nAims. We investigated the potential impact
    of frame-dragging effects on the accretion disk itself. In particular, we focused
    on its\r\nimpact on the observed variability and on the presence (and types) of
    associated QPOs.\r\nMethods. We made analytical estimates to assess the potential
    presence of a geometric warp in the inner accretion disk during state\r\ntransitions.\r\nResults.
    We show that the presence of a warp can modify the spectral-timing properties
    in a way that matches the observed transition\r\nbetween QPO types during outbursts.
    We also discuss the peculiar case of Cyg X-1, as well as how the hard-to-soft
    transition could\r\nbe driven by the warp itself.\r\nConclusions. The (expected)
    emergence of a warp provides a consistent explanation for the evolution of both
    the BBN and the QPO\r\nproperties during state transitions. This offers a first
    path toward unifying the variability of black hole X-ray binaries.@eng"
