Van Biesbroeck 8
A nearby, low-luminosity star which appears in the catalogue of ultrafaint objects discovered by astronomer George van Biesbroeck. In 1984, independent announcements were made of the discovery of an unseen companion, van Biesbroeck 8b (VB 8b), which was suspected of being a brown dwarf. The claims were made by Robert Harrington of the US Naval Observatory, based on astrometric observations, and by Donald McCarthy and colleagues at the University of Arizona, from a study using infrared speckle interferometry. Despite this persuasive double sighting, however, subsequent observations of greater sensitivity failed to uncover any further trace of the object. As a result, it is now generally accepted that VB 8b does not exist.
