A high stellar multiplicity rate amongst TESS planet candidates in the Neptunian desert using Gaia DR3 astrometry

We aim to discover whether the stellar multiplicity rate may provide information on the origin of recently discovered planets in the Neptunian desert. Using Gaia Data Release 3 astrometry, we search for common proper motion companions to 1779 known exoplanet hosts and 2927 exoplanet candidate hosts...
