Astronomers are not sure about the cause of its peculiar shape, but the current hypothesis is that the primary component of this binary is the hot core of a star that reached the end of its main-sequence life cycle, ejected most of its outer layers and then became a red giant, and is now contracting into a white dwarf.    From Wordnik.com.  ["X" Marks Puzzling Galactic Bulge | Universe Today] Reference

And if you want to cast that out as being perhaps incorrect, then you are casting out our entire present understanding of how stars evolve, which is derived only in very small part from those 20-30 yaars of observations, but in much larger part from our understanding of nuclear fusion reactions, and from observations of many, many, many main-sequence stars in the universe.    From Wordnik.com.  [A few inconvenient truths « Climate Audit] Reference
