Description The circumstellar environment of SMC X-1 contains both a highly disrupted stellar wind and an accretion disk putting it in a class containing only three X-ray pulsars. X-ray reprocessing in this material provide a probe of this material. The small absorbing column density to SMC X-1 and the excellent spectral sensitivity of XMM down to 350 eV make for an especially powerful probe of this material down to low ionization levels through spectral features from K shell transitions in carbon, nitrogen, and oxygen. We propose one 50 ksec observation of SMC X-1 over an eclipse to study the extended wind and one 30 ksec observation outside of eclipse to study material near the neutron star.

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.
