Title Is NGC 3199 the Third Wolf-Rayet Nebula with Diffuse X-ray emission?

Description X-ray emission from Wolf-Rayet (WR) nebulae is thought to be produced by the powerful winds from their central stars slamming into the circumstellar medium. Only 4 WR nebulae have been observed with the latest generation of X-ray satellites: S 308 (WR6), RCW58 (WR40), NGC6888 (WR136), and the nebula of WR16, but only S 308 and NGC6888 have been detected. ROSAT observations toward the WR nebula NGC3199 hinted at the presence of soft X-ray emission associated with this nebula, but the low angular resolution does not allow us to disentangle the different contributions to this emission. We request a 40 ks XMM-Newton EPIC-pn observation to help us study the distribution of the diffuse hot gas within the WR nebula NGC3199 around WR18.

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.
