We propose to obtain XMM-Newton observations of two dwarf novae above the periodgap, to probe and characterize the structure and nature of their boundarylayers. In particular RU Peg contains the hottest WD in a DN, and SS Aur has anear Chandrasekhar mass WD, and both are at very low inclination and haveexcellent parallax distances. The Spectra will allow us to characterize the typeof X-ray spectra exhibited by the systems, temperatures and densitites in theBLs and to map out the velocity structure of the BL by using the line widths ofX-ray lines formed at different temperatures to examine wind outflow versus highrotational velocity of the BL and the extent to which X-ray BL is deceleratedfrom the Keplerian motion of the inner disk (5,000km/s for these 2 massive WDs).

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.
