Double-Star Systems Can Be Dangerous for Exoplanets
By Mike Wall | SPACE.com – 1 hr 42 mins ago
Alien planets born in widely separated two-star systems face a grave danger of being booted into interstellar space, a new study suggests.
Exoplanets circling a star with a far-flung stellar companion — worlds that are part of "wide binary" systems — are susceptible to violent and dramatic orbital disruptions, including outright ejection, the study found.
Such effects are generally limited to sprawling planetary systems with at least one distantly orbiting world, while more compact systems are relatively immune. This finding, which observational evidence supports, should help astronomers better understand the structure and evolution of alien solar systems across the galaxy, researchers said.
"The fact that planets observed within wide binaries tend to have more eccentric (or 'excited') orbits than those around isolated stars tells us that wide binaries do often disrupt planetary systems," lead author Nathan Kaib, of Northwestern University and the University of Toronto, told SPACE.com via email.

"Thus, we believe most planetary systems are extended, with outer planets orbiting at tens of AU from their host stars," Kaib added. (One AU, or astronomical unit, equals the distance from Earth to the sun — about 93 million miles, or 150 million kilometers.)
The study was published today (Jan. 6) in the journal Nature and will be presented by Kaib at the 221st meeting of the American Astronomical Society in Long Beach, Calif., on Monday (Jan. 7).
