Aims. We investigate the physical nature of the X-ray emitting source 1RXS J165443.5−191620 through optical photometry and time-resolved spectroscopy. Methods. Optical photometry is obtained from a variety of telescopes all over the world spanning ≈27 days. Additionally, timeresolved spectroscopy is obtained from the MDM observatory. Results. The optical photometry clearly displays modulations consistent with those observed in magnetic cataclysmic variables: a low-frequency signal interpreted… Expand

The spin periods and magnetic moments of white dwarfs in magnetic cataclysmic variables
TLDR
A model of magnetic accretion is used to investigate the rotational equilibria of magnetic cataclysmic variables (mCVs) and it is demonstrated that there is a range of parameter space in the Pspin=Porb versus � 1 plane at which rotational equilibrium occurs. Expand
