Abstract We propose to observe the relatively faint new systems HT Cam, V1062 Tau and UUCol to assess their Intermediate Polar (IP) nature. XMM is particularly suitedto study the X-ray power spectra and energy distribution of faint IPs.While HTCam and V1062 Tau are hard X-ray IPs, UU Col possesses a significant soft X-raycomponent. They also cover extreme system parameters and hence are key systemsto understand whether the diversity in temporal and spectral properties of IPsis related to system parameters and evolutionary status. Also, the unprecedentedrecent discovery by XMM of a highly absorbed soft X-ray component in two newhard IPs, if confirmed in other hard systems, represents a further challenge toour understanding of accretion processes in presence of magnetic fields.

Mission Description The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
