Abstract: Carbon adds steel The edge-on disk around the nearby young star β-Pictoris is the archetypal ‘debris disk’, composed of material produced by the destruction of solid planetary bodies that may have resembled Solar System comets and asteroids. Previous work concluded that the gas should rapidly be blown away from the star, contrary to observations. New far-infrared data from NASA's FUSE satellite offer a possible explanation for this paradox: the disk gas is extremely rich in carbon, which stabilizes it against being blown away.
