Summary:
A new way to identify planetary systems around nearby stars, and a possible new explanation for the mysterious properties of certain strange white-dwarf stars, will be presented at the annual meeting of the American Astronomical Society in Washington, DC, on 7 January. The report by Penn State astronomers John Debes and Steinn Sigurdsson details several observable signatures that the researchers predict could occur as planetary systems become unstable and chaotic when a normal star like the Sun reaches the end of its life and evolves into a white dwarf.
