Description

While numerous exoplanets have now been uncovered in stellar binaries, the impact of companion stars on planet formation and evolution is still not understood. From the Gaia DR2 catalog and an extensive literature search, we compiled the largest list to date of planets orbiting stars in visual comoving binaries out to 200 pc, providing a broad overview of exoplanets in resolved binary systems. Here, I present results of raw population trends seen in the gathered compilation, which allows to investigate planet physical and orbital properties as a function of the multiplicity of the host stars, and to understand the effects of binary properties on the resulting architectures of planetary systems.
