<p>The highly transient multi-wavelength system AE Aqr consists of a fast rotating highly magnetic WD, accreting mass from a K3-5 secondary companion. This magnetic CV has a characteristic orbital period of 9.88 h, and is in a propeller state. The turbulent interaction between the fast spinning WD magnetosphere and the accretion flow is believed to play a crucial role in the multi-wavelength emission in the system. We have analysed the system's X-ray lightcurves and spectra from data observed with Chandra and Swift-XRT, and the results of this study show that the X-ray characteristics are unique. In this paper, the results of the analysis will be discussed, with the view to propose suitable models for the X-ray emission mechanisms.
