Description GT- The X-ray spectrum of the eclipsing high mass binary Vela X-1
exhibits discrete spectral features produced through photoionization
of the stellar wind by hard X-rays from the neutron star companion.
We plan an out-of-eclipse observation of Vela X-1 to measure velocity
fields, temperatures, and densities of the emission line regions
and to constrain some of the key parameters that characterize
the structure of the circumsource material.

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.
