Do the Astronomical Limbo

Spaceflightnow is carrying this article detailing the discovery of a previously unknown sort of stellar object. Found by examining the binary system EF Eridanus using the Gemini North and Keck II telescopes, this object appears to have once been a less massive binary partner of what is now a white dwarf. The current theory postulates that at some point these were both regular stars, with one "sucking" mass off the other one, I guess like a kid with a lollypop. What's left of the less massive member is too small to be a star but far to big to be even a brown dwarf.
