DESCRIPTION:Speakers: Elizaveta Ryspaeva (Saint Petersburg State Universit
 y)\nAE Aquarii has been known as one of the most enigmatic magnetic Catacl
 ysmic Variables on various aspects\, including large optical flares and fl
 ickering large radio flares\, TeV gamma-ray emissions and X-ray emission. 
 AE Aquarii is a close binary system composed of a magnetized white dwarf a
 nd a Roche-lobe filling K3IV red dwarf. A white dwarf has a very short rot
 ational period about 33.08 s. We  have made independence timing analisys o
 f archival AE Aquarii X-ray observation\, obtained using orbital observato
 ries «XMM-Newton» and «Chandra» in 2001 and 2005 respectively. We comp
 ared our results with published data. Period searching with different nume
 rical methods confirmed the presence of 33-s regular X-ray pulsations. Als
 o we confirmed that pulsations with a period of 16.5 s\, visible in optica
 l and UV ranges\, absents in the X-ray part of AE Aquarii spectrum. It can
  means that an X-ray emission comes from the one pole of white dwarf surfa
