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.
Two-star systems occur commonly throughout our galaxy; indeed, astronomers think the Milky Way harbors about as many binary systems as single stars. Recently, astronomers have begun discovering planets in binary systems, some of them "Tatooine" worlds with two suns in their skies, like Luke Skywalker's home planent in the "Star Wars" films.
If a wide binary lasts long enough, it eventually will find itself with a very high orbital eccentricity at some point in its life.”
Often, exoplanets just get tugged from their orginal, near-circular orbits into more eccentric ones, the simulations showed.
