Abstract | Superbubbles (SBs) are formed by the combined actions of stellar winds andsupernova explosions from massive stars in OB associations. These objectscontribute significantly to the hot gas component of a galaxys interstellarmedium (ISM), as well as affecting the structure of the ISM to large scales. Wepropose XMM-Newton observations of two X-ray prominent superbubbles, N57 andN206, in the Large Magellanic Cloud. From these X-ray spectral data, we willinvestigate (a) the energy budgets of the SBs, and whether those are consistentwith expected stellar-wind inputs; (b) the required input of SNRs to these SBsto obtain the observed energies; and (c) enhanced abundances indicating recentenrichment by SN ejecta. |

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. |
