| Description | GT-The cluster IC 2391 is an ideal target to study the decline of X-ray flux with age, the existence of a related softening of the X-ray spectrum with age, and of a saturation level of the X-ray surface flux: it is so young (age virgul30 Myr) that solar-type members have just arrived on the main-sequence, they have not yet spun down, and they are very active. Being significantly younger than other star clusters the observation of IC 2391 will provide data crucial to understand the evolution of stellar coronae spectra. The high quality XMM spectra will likely reveal a thermal coronal structure more complex than that obtained with other instruments so far. IC 2391 has been the target of surveys and detailed optical and photometric studies in the optical band. |

| 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. |
