Description Recent population studies of M31 novae with supersoft X-ray source counterparts have suggested important population trends and correlations between optical and X-ray parameters. These correlations could become a vital tool for an effective planning of future nova observations. A preliminary multi-parameter analysis promised a better understanding of nova physics but suffered from small number statistics. This project will use joint XMM-Newton (74ks) and Swift (40ks) pointings of M31 novae (with observing strategies tailored to the properties of the individual object) to test predictions based on the existing data. We will only target very fast (disk) novae with well determined optical spectra and light curves to increase the small sample of novae with multi-parameter data.

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.
