|Title||The calm after the storm: the cooling phase of novae|
|Author||Dr Marina Orio|
|Description||The secular evolution of classical and recurrent novae determines the outburst outcome and the final fate of interacting binary white dwarf systems. We have monitored novae that were already well studied in outburst, while they cool and resume accretion, discovering interesting facts. We uncovered evidence thatmagnetic, intermediate polar white dwarfs may be frequent in novae. We also found novae in which a region on the white dwarf surface remains as hot as in outburst for years, and in one case we have observed it completely cooling. We propose to observe V2491 Cyg and KT Eri as they settle into quiescence, to study this phenomenon and understand its root cause, including the possible connection with the magnetic field.|

|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.
