Description We propose two 60 ks observations of the large mixed-morphology supernova remnant HB9. ROSAT observations detected a large, bright, clumpy region of X-ray emission towards the southeast of the remnant, with strong X-ray emission towards the center and faint emission reaching the edge of the radio shell. HB9 is thought to be interacting with a MC based on the detection of CO emission towards the northeast of the remnant. The clumpy nature and irregularity of the X-ray emission indicates an inhomogeneity of the pre-supernova medium and a density gradient from the north to the south of the remnant. These proposed observations will provide the first CCD-quality X-ray spectra from the remnant, allowing us to carry out a spatially resolved spectral analysis of the X-ray emitting plasma in HB9.

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.
