| Description | For a binary to be a recurrent nova (RN), it must contain a massive white dwarf (WD) near the Chandrasekhar limit, making it a candidate progenitor of type Ia supernova. Although the WD masses and the accretion rates in RNe must all be similarly high, the X-ray properties of RNe with red-giant donar stars can be wildly different, ranging from hard and luminous (virgul1e34 ergs/s) to softer and significantly fainter (below 1e32 ergs/s). Such drastic differences may indicate that a third parameter, such as the spin period or the core temperature of the WD, may play an important role. Here we propose quiescent X-ray observations of 4 RNe in cataclysmicvariable (CV) systems to test if a third parameter indeed exists. |

| 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. |
