Abstract | We propose to observe the young (2-6 Myr) open cluster around the hot (O8III)star lambda Orionis. We will obtain a high-resolution spectrum of the centralhot star with RGS as well as EPIC imaging and spectra of the surroundingcluster. Our goal is to study the X-ray properties of the lambda Ori wind and ofpre-main sequence cluster members, and to compare them with those of the twinsigma Ori cluster, in order to investigate the influence of the ambientenvironment on stellar evolution and activity. |

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. |
