Abstract	A protoplanetary system consisting of at least two giant planets surrounds theyoung nearby Herbig Be star HD 100546. The inner protoplanet orbits within 13 AUof the star and is exposed to strong stellar UV and X-ray radiation. Thedetection of very warm disk gas provides evidence that stellar heating isaffecting physical conditions in the planet-forming environment. Chandradetected HD 100546 in two short 2.6 ks exposures but there are insufficientcounts to reliably extract spectral parameters. We propose a deeper follow-upobservation with XMM to obtain a spectrum of sufficient quality to determine theX-ray absorption, temperature distribution, and luminosity. We will use the XMMdata to determine the X-ray heating and ionization rates in the disk.

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.
