| 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. |
