This article in Physics. org reports that an international team of astrophysicists has shown through computer simulations that distant orbiting binary stars “wreak havoc” on planetary systems of companion stars.

“Planetary systems with very distant binary stars are particularly susceptible to violent disruptions, more so than if they had stellar companions with tighter orbits around them.”

Here’s more from the studies’ lead author Nathan Kaib on distant binary star disturbance:


“This causes their stellar orbits to constantly change their eccentricity – their degree of circularity. If a wide binary lasts long enough, it will eventually find itself with a very high orbital eccentricity at some point in its life.”
