|Title||DG Tau and its jet in time|
|Author||Dr P. Christian Schneider|
|Description||The classical T Tauri star DG Tau drives a spectacular jet which contains plasma with temperatures ranging from 10^4 to >10^6 K within the innermost 50 AU. Although, the luminosity of the jet related X-ray emission varies by almost a factor of two within six years, no proper-motion could be observed as for the outer emission regions of the jet. We propose to monitor the luminosity evolution with two 25 ks exposures in order to derive the timescale on which such variations occur. With the large multi-wavelength campaign currently underway, this represents the unique chance to relate the evolution of the soft X-ray emission with other jet tracers and thus to decide whether the X-ray emission is connected to the optically observed outflow of only 10^4 K.|

|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.
