Description In recent UV and optical studies the interacting binary star, QU Car, has been shown to be the most luminous nova-like variable star ever observed and may even be as luminous as the supersoft X-ray sources. It also displays spectral characteristics that would suggest a close similarity to the supersoft sources. We propose to measure the X-ray brightness of QU Car with XMM to establish decisively whether it is a supersoft X-ray source and, if it is not, to understand just how a luminous interacting binary system with such a high rate of mass transfer avoids being a supersoft.

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.
