We propose to localize and observe the likely degenerate companion to the 17-pcdistant star HD 43162. This previously unknown object, discovered by us in EUVEobservations, 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 brightX-ray counterpart in quiescence. XMM observations will therefore allow us tolocalize the compact object to arcsecond precision, enabling deep counterpartsearches. In addition, we will collect a high-quality X-ray spectrum toconstrain physical models for the source. If the object is a neutron star orblack hole, it is the closest known such compact object, and will be subject todetailed multiwavelength study for years to come.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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.
