Abstract:We intended to quantify the impact of stellar multiplicity on the presence and properties of exoplanets. We investigated all exoplanet host stars at less than 100\,pc using the latest astrometric data from Gaia DR3 and advanced statistical methodologies.
We complemented our search for common proper motion and parallax companions with data from the Washington Double Star catalogue and the literature.
After excluding a number of systems based on radial velocity data, and membership in clusters and open associa… Show more
