Title X-ray emission from an adolescent classical T Tauri star


DOI 10.5270/esa-ww7ia33
Author Dr Antonio Maggio
Description We propose to perform high-resolution X-ray spectroscopy of MP Muscae, a classical T Tauri star with an age of about 10 Myr, and hence quite old for its class. In fact, MP Mus is the only known star of this age with evidence of an accretion disk, found in a survey of the Lower Centaurus-Crux subgroup in the Scorpius- Centaurus association. Moreover, this star also shows evidence of a cold dusty disk, as indicated by excess emission at IR and mm wavelengths. The proposed observation will allow us to address several issues concerning the evolution of the X-ray emission in pre-main-sequence stars, the mechanism(s) of such emission, the element abundances of the emitting plasma, and the influence of high-energy radiation on the surrounding medium where planetary formation is likely occurring.

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.
