|Title||X-ray portrait of a massive star with magnetic personality: xi1 CMa|
|Author||Dr Lidia Oskinova|
|Description||We propose a 100 ks observation to obtain the RGS spectrum of the magnetized massive star xi1 CMa. According to the models, the hot plasma shall be found in the vicinity of the Alvfen radius, which is at 50Rstar for this star. Measuring the line species and fluxes as well as line ratios in He-like ions will allow us to establish the plasma temperatures, emission measure and magnetospheric volume. The RGS spectrum of xi1 CMa will provide an important test of models for the X-ray generation in massive magnetic stars, which are being challenged by low resolution X-ray data.|

|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.
