Description | Following NRCO18, as part of the long-term effort to monitor the RGS sensitivity and possible contamination, the star zeta Puppis is an ideal target because of the exceptional strength of its NVI and NVII lines at about 25 and 30A respectively. So far, XMM has not been able to detect any variability above the few percent level. It is visible for 2 months every 6 months and for this programme, I propose a further 60ks observation with a small pointing adjustment in order for the NVI and NVII lines to be clear of chip gaps, as much as possible, in both RGS instruments. |

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. |
