Multiple Periodicities and Spectral Components in New Intermediate Polars

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 Xray power spectra and energy distribution of faint IPs.While HTCam and V1062 Tau are hard Xray IPs, UU Col possesses a significant soft Xraycomponent. 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 Xray 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. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
