Astrophysicist Dr Markus Mugrauer of Friedrich Schiller University Jena, Germany, has discovered many new multiple star systems that contain exoplanets. For this, he searched more than 1,300 exoplanet host stars. He found that 15 per cent of those stars have at least one companion star, which is only about half the frequency expected for solar like stars. This could indicate that the influence of several stars in a system disrupts the process of planet formation.
