Description GT-chi1 Ori is a solar analog with an age of only about 300 Myrs. Its consequent
activity is intermediate between zero-age main-sequence stars and the Sun.
This target is part of a study on the .Sun in Time. in which we investigate the
decline of coronal activity of a solar analog with time. Important aspects
concern the emission measure distribution, the abundance pattern that might be
activity dependent, and flare variability studies with respect to temperatures,
abundances, densities, and mass motions. The pn and one MOS will be used in
TIMING mode, the pn with the medium filter to optimize the detection of soft
photons, and the MOS with the thick filter.

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.
