| Description | Massive stars lose mass throughout their evolution - fast winds during the main sequence (MS) and Wolf-Rayet (WR) phases, and slow winds during the red supergiant or luminous blue variable phase. Fast winds from single stars can blow MS interstellar bubbles and WR circumstellar bubbles. Whereas the diffuse X-ray emission from shocked stellar winds has been detected in WR bubbles, MS bubbles have never been detected. We request XMM-Newton EPIC observation of the Bubble Nebula, the bubble around BD+60 2522 in NGC7635, to search for diffuse X-ray emission and to assess the origin of the X-ray emission detected by ROSAT at the central star and the intriguing Northern radio arc unveiled by VLA observations. The observations will be assessed using our radiation-hydrodynamic models. |

| 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. |
