Abstract | We propose to survey the X-ray emission of the pre-main sequence Herbig Ae/Bestars. Speculations concerning the origin of this X-ray emission have beenoffered. They include processes involving massive accretion disks, magneticstellar coronae, strong stellar winds, or attribute the X-ray emission to alow-mass companion. We intend to observe unbiased samples of Herbig Ae/Be starswith the XMM EPIC pn camera: one sample of such stars showing signs of massiveaccretion disks, one sample with signatures of stellar winds, and one sample ofbinary systems including one Herbig star and one T Tauri companion. Differencesin detection rates, X-ray luminosity distributions, X-ray energy distributionsbetween these three samples will enable us to test the various interpretations. |

Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
