Description Superbubbles (SBs) are formed by the combined actions of stellar winds and supernova explosions from massive stars in OB associations. These objects contribute significantly to the hot gas component of a galaxy.s interstellar medium (ISM), as well as affecting the structure of the ISM to large scales. We propose XMM-Newton observations of two X-ray prominent superbubbles, N57 and N206, in the Large Magellanic Cloud. From these X-ray spectral data, we will investigate (a) the energy budgets of the SBs, and whether those are consistent with expected stellar-wind inputs; (b) the required input of SNRs to these SBs to obtain the observed energies; and (c) enhanced abundances indicating recent enrichment by SN ejecta.

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.
