【 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 s rotational period of white dwarf in the system. In addition, we confirmed that X-ray pulsations with a period of 16.5 s, which were detected in optical and UV ranges, absent in AE Aquarii spectrum. This may mean that the X-ray emission comes from one of the poles of white dwarf surface.
