|Title||The Fainter Late-Type WTTS Population in the Sco-Cen Star Formation Region|
|Author||Dr Martin Turner|
|Description||GT-We propose a deep EPIC observation of the nearby SFR Upper Sco-Cen where medium-deep pointed ROSAT observations (Sciortino et al. 1998) have shown that the shallow limiting sensitivity either of Einstein and RASS data prevents the sufficient sampling of the lowest mass and X-ray fainter stars strongly biasing the estimate of the IMF. The proposed XMM observation will allow us to detect essentially all of the X-ray emitting population and to derive a reliable IMF at low mass end. For all the known stars in the field of view we will also obtain EPIC spectra of quality better than any PMS ASCA, and even ACIS, spectra with the same exposure time. This will allow us to constrain the physical conditions in PMS coronae and to compare them with those of other coeval stellar samples.|

|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.
