Unveiling X-ray properties of new intermediate polars
Résumé
We present first X-ray observations with the XMM-Newton satellite of the new magnetic Cataclysmic Variables HT Cam, UU Col and RX J2133+51. Strong rapid X-ray pulses reveal the rotational period of the accreting white dwarf thus unambiguously confirming these systems as true members of the Intermediate Polar class. These systems also reveal complex properties which make Intermediate Polars an intriguing class still to be fully explored.
