| Abstract | We proposed to observe the quiescent nova CP Pup. This system is a known X-raysource at low inclination, so it is an ideal targets to study how accretionoccurs. CP Pup has a short orbital period, allowing a useful comparison withlonger period systems that have been observedin X-rays. Spectroscopy will beused to measure mdot and test theories of secular evolution, timing analysiswill be used to localize and constrain the size of the emitting region. |

| 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. |
