Description The supernova remnant 0454-67.2 in the northwest wing of the Large Magellanic Cloud is cooling and has faded to the point where most of the X-ray emission is in lines of O and Fe below 1 keV. These energies and the remnant geometry are well suited to the XMM RGS spectrometer, making it possible to get important information from this low-luminosity object. We will measure the abundance and temperature of O, Ne, and Fe in the central region and confirm (or not) the Type Ia identification. We will then use the measured line ratios to directly estimate the ionization age of the remnant and, using the morphology measured by EPIC and by Chandra, calculate the mass of Fe in the central region. There may also be evidence for overionized plasma as in some .mixed morphology.remnants.

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.
