Description We propose Target of Opportunity (ToO) observations to characterise the supersoft X-ray emission of optical novae in the disk of M 31 with four 20 ks XMM-Newton EPIC observations during July 2010 to mid-August 2010 and January 2011 to mid-February 2011. These observations will allow to perform spectral analysis of M 31 disk novae during their supersoft X-ray source state (SSS) and to determine effective temperatures and luminosities. The probability of triggering all four observations on four different novae is high. Our observations will double the number of M 31 disk novae with known SSS spectra. This will help to study the differences between bulge novae and disk novae in the X-ray regime.

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.
