Description We propose for XMM-Newton observations of two highly extincted fields in the
ChaII star forming region. Our aim is to complete the census of cloud members
using X-ray emission as a means to discover young stars. A clear assessment of
the full stellar population is essential to establish the evolutionary state of
a star forming cloud. ChaII seems to represent a comparatively young phase where
many stars retain their disks. But a large number of low-mass members may still
be hidden in the dark parts of the cloud. In contrast to earlier X-ray
instrumentation XMM-Newton provides enough sensitivity and an extended spectral
range allowing to penetrate the highly absorbed parts of ChaII, and study the
stellar population across regions of high and varying extinction.

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.
