Abstract	The close binary supersoft X-ray source CAL 83 is a most promising candidate ofSN Ia progenitors. Our XMM-Newton and Chandra observations show a massive whitedwarf, exhibit large amplitude short-term variations of the X-ray flux, andestablish definitively its recurrent nature. We propose now to conduct acampaign with EPIC and OM on XMM-Newton to substantiate the correlation betweenX-ray and optical variations on a short, medium, and long-term basis. Thiscampaign will trace the physical relation between the accretion disk and thewhite dwarf, and will discriminate between several models explaining the originof CAL 83 off-states. XMM-Newton data will offer unique and timely insights intoaccretion and unstable nuclear burning during the last evolution stages of SN Ia progenitors.

Mission Description	The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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.
