Abstract	We propose to use XMM-Newton to obtain the first high-resolution X-ray spectrumof the peculiar magnetic A-type star IQ~Aur. From previous X-ray observationsIQ~Aur is known as a strong, but very soft X-ray source. In addition to theHAeBe star HD~163296, IQ~Aur is a very good candidate for an A-type star withintrinsic X-ray emission. The XMM-Newton RGS spectrum will strongly constrainthe location of the X-ray emission site from a measurement or upper limit to thestrength of the OVII f/r line ratio, the overall RGS spectrum will determine theelemental abundances, which may be far from solar, and finally, the phasecoverage of the EPIC data will be sufficient to search for a rotationalmodulation of IQ~Aurs X-ray flux.

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.
