Binary Star Evolution as a Driver of Planet Formation

What can binary star systems teach astronomers about the formation and evolution of planets orbiting them? This is what a recent study published in Nature hopes to address as a team of scientists investigated past studies that claimed a specific binary star system could host a planet demonstrating a retrograde orbit, meaning it orbits in the opposite direction of the star’s rotation. This study has the potential to help scientists better understand binary and multiple star systems, specifically the formation and evolution of their planets and what this could mean for finding life beyond Earth.
