| Description | Many, if not all, Herbig Ae/Be stars (HAeBes) are known to be strong X-ray emitters, however, the origin of the observed X-ray emission is unclear. In a few cases it can be attributed to unseen companions, but in the case of the HAeBe star HD 163296 binarity can be excluded. CCD spectra from imaging observations of HD 163296 can be well fitted by a single, cool (T=0.5 keV) thermal model, very much in contrast to typical active stars. We propose to obtain a high SNR, high spectral resolution grating spectrum in order to carry out direct plasma line diagnostics already successfully used in classical T Tauri stars to physically characterise the X-ray emission regions in HD 163296 and to solve the mystery of the X-ray emission mechanism in HAeBes. |

| 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. |
