Concordance cosmogony makes that prediction. It is, however, a prediction of extrasolar planetary system architecture as yet untested by direct observation for main sequence stars other than the Sun. To provide such a test, we ...Continue Reading

Ultraluminous X-ray sources (ULXs) are bright, irregularly variable, non-nuclear, X- ray sources with apparent luminosities exceeding the Eddington limit for stellar- mass black holes. There is great interest in ULXs because they may represent a n ...Continue Reading
