| Description | GT- Observations with ROSAT and ASCA have shown that X-rays can be efficiently detected from young objects deeply embedded in molecular clouds, extinction up to Av=40 or more, implying substantial X-ray luminosities: Lx=1E32-1E34 erg-s. X-rays are expected to strongly influence the physical state of the protostellar gas and dust, with new implications for the early solar system. We propose to obtain 1-10 keV spectra of two evolved protostars already known in X-rays, in order to accurately measure the plasma temperature and the extinction; we will also attempt to detect for the first time a very young protostar, still embedded in a thick circumstellar envelope. |

| 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. |
