Magnetic fields, whether originating from the compact object or the accretion disc, play an important but often neglected role in shaping the geometry and variability of accretion flows. Recently quasi-periodic variability in accreting white dwarfs has pointed towards a mechanism of driving the precession of the inner accretion flow through misaligned accretor magnetic field. This is presenting an alternative explanation for the well known quasi-periodic oscillations (QPOs) in X-ray binaries and has shown promise in application to QPOs in pulsating ultraluminuos X-ray sources with extremely high magnetic fields. However, further detections of these QPOs in accreting white dwarfs are needed to test their behaviour and adherence to the model. However, the prevalence and properties of such QPOs in accreting white dwarfs remain poorly constrained due to the limited number of detections. Here, we report the detection of a new QPO in the WZ Sge type dwarf nova BW Scl and present a comprehensive reanalysis of previously detected accreting white dwarf (AWD) QPOs without reliance on fiducial parameter assumptions. These results demonstrate that QPOs can be used to place constraints on magnetic field strengths and other system properties of nominally non-magnetic white dwarfs.
