Skeleton star gets gobbled Astronomers using NASA's Swift and Rossi X-Ray Timing Explorer (RXTE) satellites have discovered a stellar skeleton, a remnant of a dying star that is being consumed by its pulsar companion. So little of the star's original material is left that it now barely masses more than Jupiter.â¦
