Description We propose to test the hypothesis that the cataclysmic variables HS Cam (RX J0719.2+6557) and HT Cam (RX J0757.0+6306) are two short-period intermediate polars. While an alternative interpretation is possible for each source based on the optical data, XMM-Newton observations can easily provide the distinctive features: (i) the shape of the orbital variation of the X-ray intensity, and (ii) coherent X-ray pulsations caused by the spin of the white dwarf. We therefore propose short 15 and 13 ksec observations of these sources which is sufficient to identify these features.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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.
