Circumbinary castaways: Short-period Binary systems can Eject Orbiting Worlds

This artist's concept illustrates Kepler-16b, the first planet known to orbit two stars - what's called a circumbinary planet. The planet, which can be seen in the foreground, was discovered by NASA's Kepler mission. New research from the University of Washington indicates that certain shot-period binary star systems eject circumbinary planets as a consequence of the host stars' evolution.

Planets orbiting “short-period” binary stars, or stars locked in close orbital embrace, can be ejected off into space as a consequence of their host stars’ evolution, according to new research from the University of Washington...
