Euve J0614-2354, Xmm-Newton Proposal 02061901

Scientific paper

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.
