|Title||LH9 and LH10: two LMC OB associations of different ages in one shot|
|Author||Prof Keith Mason|
|Description||GT- Wang & Helfand (1991) reported the detection of diffuse X-ray emission from OB associations in the LMC with the Einstein observatory. Most of these associations are surrounded by H alpha rings or complex filaments, some of them, the so-called supergiant shells, extending over up to 1 kpc. Several of the associations exhibit shell-like X-ray morphologies which generally follow the H alpha emitting gas. According to the authors a significant part of the energy is provided by supernova remnants hitting the dense shells of young bubbles. This proposal is part of a comprehensive program aimed at the study of stars in different evolutionary stages and in environments with differeent metallicities.|

|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.
