Description We propose to localize and observe the likely degenerate companion to the 17-pc distant star HD 43162. This previously unknown object, discovered by us in EUVE observations, flared to a luminosity of 3.6E+31 erg-s for a duration of 200s. Inspection of ROSAT All-Sky Survey data indicates that the object has a bright X-ray counterpart in quiescence. XMM observations will therefore allow us to localize the compact object to arcsecond precision, enabling deep counterpart searches. In addition, we will collect a high-quality X-ray spectrum to constrain physical models for the source. If the object is a neutron star or black hole, it is the closest known such compact object, and will be subject to detailed multiwavelength study for years to come.

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.
