Description We propose to observe three supersoft X-ray sources in the LMC. All of them are X-ray variable: one is a classical nova, while the other two have been observed to move in and out the ROSAT-Einstein windows, varying energy peak and-or flux. The low interstellar absorption to the LMC allows optimal conditions for observations in the supersoft energy range. The exceptional sensibility of the EPIC camera at low energy will allow us to nail down for the first time i the L(x) vs. T(eff) plane the physical behaviour of these intriguing systems containing an exceptionally hot, shell-hydrogen burning white dwarf.

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.
