摘要：

We reanalysed the archival X-ray observations of double system AE Aquarii, obtained using orbital observatories "XMM-Newton" and "Chandra" in 2001 and 2005 respectively. We made an independent timing analysis with two numerical methods. Our result confirmed the presence of 33 ws rotational period of white dwarf in the system. In addition, we confirmed that Xray pulsations with a period of 16.5 s, which were detected in optical and UVranges, absent in AE Aquarii spectrum. This may mean that the X-ray emission comes from one of the poles of white dwarf surface.
