Title Deciphering the X-ray Emission of the Nearest Herbig Ae Star


DOI 10.5270/esa-ij827gm
Author Dr Stephen Skinner
Description ROSAT detected X-ray emission from more than a dozen Herbig Ae-Be stars (intermediate mass pre-main-sequence stars), but its origin is not yet understood. Several explanations have been proposed, but there is presently no X-ray spectrum of sufficient quality to rigorously constrain the theory. We propose to obtain an EPIC pn spectrum of HD104237, the closest Herbig Ae star known. This spectrum will provide the accurate temperature discrimination needed to test competing models based on shock processes and wind-fed magnetospheres (which predict only soft emission below 1 keV) and coronal models in which hotter plasma is expected.

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.
