| Description | The origin of X-ray emission in Herbig Ae/Be stars, intermediate-mass pre-main sequence stars, is still disputed, as these objects are not expected to be able to drive a dynamo to sustain magnetic activity. Their progenitors, the intermediate-mass T Tauri stars (IMTTS), cover the transition from a convective core to a fully radiative one, which is important for the presence of a magnetic field, and thus their X-ray activity. At the same time IMTTS are still accreting from their protoplanetary discs, which also contributes to their X-ray output. We have compiled a (to our knowledge complete) sample of 75 IMTTS, and aim to compare their X-ray properties in relation to their masses, ages and accretion rates. We apply for an XMM survey for 29 IMTTS to complete the sample coverage in X-rays. |

| 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. |
