Description We request a single, unphased, 5-ks snapshot observation of the southern WR
variable star WR 71. The binary status of this object is uncertain, but our
recent observations show that its spectropolarimetric features resemble those of
known WR+O binary systems. We seek to establish whether WR 71 displays bright
X-ray emission similar to known colliding-wind binaries. If so, we will propose
follow-up observations to characterize its X-ray spectrum and shed further light
on its binary status.

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.
