Title Are Magnetic He--W-Si Stars Intrinsic X-Ray Emitters

Description We propose to observe 3 Magnetic Chemically Peculiar stars in order to get moderately-exposed PN spectra of two of them known to be X-ray sources, and to try and detect emission from the third star. These X-ray sources are moderately faint and spectrally soft, and hence the XMM-Newton EPIC is the best instrument to observe them. We will analyze the spectra for evidence that the X-ray emitting plasma is intrinsic to the MCP stars rather than from unresolved low-mass companions, e.g., by determining elemental abundances to see if they are significantly non-solar. We will also study the X-ray emission, both over the entire detected energy range and as function of energy, as a function of time, and will also apply for supporting contemporaneous VLA observations.

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.
