TL;DR
This paper proposes a magnetohydrodynamic model for low-frequency quasi-periodic oscillations in black hole X-ray binaries, linking oscillation frequencies to disk flux and Alfvén wave dynamics.
Contribution
It introduces a novel MHD-based model that explains LFQPOs and their correlation with disk radiation flux in black hole X-ray binaries.
Findings
LFQPO frequencies fit by toroidal Alfvén wave oscillations
Positive correlation between LFQPO frequencies and disk flux
Model explains observed LFQPO behavior in BHXBs
Abstract
A model of low-frequency quasi-periodic oscillations (LFQPOs) of black hole X-ray binaries (BHXBs) is proposed based on the perturbed magnetohydrodynamic (MHD) equations of accretion disk. It turns out that the LFQPOs frequencies of some BHXBs can be fitted by the frequencies of the toroidal Alfv\'en wave oscillation corresponding to the maximal radiation flux. In addition, the positive correlation of the LFQPO frequencies with the radiation flux from accretion disk is well interpreted.
