| Description | Our Swift X-ray-UV monitoring campaigns have shown that the evolution of novae is much more complex than previously believed. We have observed a high degree of variability in X-rays for many novae. We focus on the supersoft source phase, which is the brightest phase in X-rays. The aim is to complement our Swift observations with studies of short-term variations from which the spin period of the white dwarf can be determined and to obtain a high-resolution X-ray spectrum from which the chemical composition and the dynamics of the expanding shell can be determined. Since all observed novae have behaved differently, we need to observe many novae in order to achieve a more general understanding. We request 60ks to observe the next nova that has a Swift count rate of 0.5 cps or more. |

| 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. |
